Rabbi Akiva: The Man, the Myth, the Legend

(2) What were Akiva's beginnings? It is said: Up to the age of forty, he had not yet studied a thing. One time, while standing by the mouth of a well in Lydda, he inquired, "Who hollowed out this stone?" and was told, "Akiva, haven't you read that 'water wears away stone' (Job 14:19)? - it was water falling upon it constantly, day after day." At that, Rabbi Akiva asked himself: Is my mind harder than this stone? I will go and study at least one section of Torah. He went directly to a schoolhouse, and he and his son began reading from a child's tablet. Rabbi Akiva took hold of one end of the tablet, and his son of the other end. The teacher wrote down alef and bet for him, and he learned them; alef to tav, and he learned them; the book of Leviticus, and he learned it. He went on studying until he learned the whole Torah. Then he went and sat before Rabbi Eliezer and Rabbi Joshua. "My masters," he said, "reveal the sense of Mishnah to me." When they told him one halakhah, he went off to reason with himself. This alef, he wondered, what was it written for? That bet - what was it written for? This teaching - what was it uttered for? He kept coming back, kept inquiring of Rabbi Eliezer and Rabbi Joshua, until he reduced his teachers to silence.

It was taught in a baraita that Rabbi Akiva said: When I was an ignoramus I said: Who will give me a Torah scholar so that I will bite him like a donkey? His students said to him: Master, say that you would bite him like a dog! He said to them: I specifically used that wording, as this one, a donkey, bites and breaks bones, and that one, a dog, bites but does not break bones.

§ In connection to the above incident concerning the poverty of scholars and their potential to become wealthy through remarkable circumstances, the Gemara relates an incident: Rabbi Akiva became betrothed to the daughter of bar Kalba Savua. When bar Kalba Savua heard about their betrothal, he took a vow prohibiting her from eating all of his property. Despite this, she went ahead and married Rabbi Akiva. In the winter they would sleep in a storehouse of straw, and Rabbi Akiva would gather strands of straw from her hair. He said to her: If I had the means I would place on your head a Jerusalem of Gold, a type of crown. Elijah the prophet came and appeared to them as a regular person and started calling and knocking on the door. He said to them: Give me a bit of straw, as my wife gave birth and I do not have anything on which to lay her. Rabbi Akiva said to his wife: See this man, who does not even have straw. We should be happy with our lot, as we at least have straw to sleep on. She said to him: Go and be a student of Torah. He went and studied Torah for twelve years before Rabbi Eliezer and Rabbi Yehoshua. At the completion of the twelve years, he was coming home when he heard from behind his house that one wicked person was saying to his wife: Your father behaved well toward you. He was right to disinherit you. One reason is that your husband is not similar to you, i.e., he is not suitable for you. And furthermore, he has left you in widowhood in his lifetime all these years. She said to him: If he listens to me, he should be there for another twelve years. Rabbi Akiva said: Since she has given me permission through this statement, I will go back and study more. He turned back and went to the study hall, and he was there for another twelve years. Eventually he came back accompanied by 24,000 pairs of students. Everyone went out to greet him, as he was by then a renowned teacher, and she too arose to go out to greet him. That wicked person said to her: And to where are you going? As she was excessively poor, she was not dressed in a grand manner, as fit for the wife of one so esteemed. She said to him: “A righteous man regards the life of his beast” (Proverbs 12:10); he knows that I am in this state as a result of my dedication to him. She came to present herself before Rabbi Akiva, but the Sages tried to fend her off, as they were unaware of her identity. He said to them: Leave her. Both my Torah knowledge and yours are hers. When bar Kalba Savua heard that the famous man was his son-in-law, he came before halakhic authorities and requested the dissolution of his vow, and it was dissolved. The Gemara adds: Rabbi Akiva became wealthy from six things. First, from the money he received from Kalba Savua after his vow was dissolved. Second, he gained money from the ram of a ship [eila disfineta], as craftsmen would fashion a sculpture of a type of sheep for every ship, which would be placed on its bow, and which would be used to conceal money. On one occasion, the sailors forgot this ram on the seashore, and Rabbi Akiva came and found it with the money stored inside. And third, he became wealthy from a log [gavza] of wood, as on one occasion he gave four dinars to sailors and said to them: Bring me something worthwhile. And they found only a log of wood on the seashore. They brought it to him and said to him: May our master wait with this until we bring a more worthy item. He found that the log was full of dinars, as on one occasion a ship sunk and all the merchandise, i.e., the money, owned by the people on the ship was placed in that log, and it was found on that occasion by the sailors. Rabbi Akiva became wealthy from a convoy of Ishmaelites [Serukita]. And he became wealthy from a certain lady. Rabbi Akiva borrowed money from a lady and said that God would be his guarantor. When it came time to return the loan, the king’s daughter became insane and threw a purse of jewelry into the sea, which was found by that lady. She told Rabbi Akiva that his guarantor had paid his debt and she allowed him to keep the loan. And Rabbi Akiva also grew wealthy from the wife of Turnus Rufus, who converted and gave him her money, and from Ketia bar Shalom, a Roman minister who bequeathed his fortune to him. §

The Gemara further relates: Rabbi Akiva was the shepherd of ben Kalba Savua, one of the wealthy residents of Jerusalem. The daughter of Ben Kalba Savua saw that he was humble and refined. She said to him: If I betroth myself to you, will you go to the study hall to learn Torah? He said to her: Yes. She became betrothed to him privately and sent him off to study. Her father heard this and became angry. He removed her from his house and took a vow prohibiting her from benefiting from his property. Rabbi Akiva went and sat for twelve years in the study hall. When he came back to his house he brought twelve thousand students with him, and as he approached he heard an old man saying to his wife: For how long will you lead the life of a widow of a living man, living alone while your husband is in another place? She said to him: If he would listen to me, he would sit and study for another twelve years. When Rabbi Akiva heard this he said: I have permission to do this. He went back and sat for another twelve years in the study hall. When he came back he brought twenty-four thousand students with him. His wife heard and went out toward him to greet him. Her neighbors said: Borrow some clothes and wear them, as your current apparel is not appropriate to meet an important person. She said to them: “A righteous man understands the life of his beast” (Proverbs 12:10). When she came to him she fell on her face and kissed his feet. His attendants pushed her away as they did not know who she was, and he said to them: Leave her alone, as my Torah knowledge and yours is actually hers. In the meantime her father heard that a great man came to the town. He said: I will go to him. Maybe he will nullify my vow and I will be able to support my daughter. He came to him to ask about nullifying his vow, and Rabbi Akiva said to him: Did you vow thinking that this Akiva would become a great man? He said to him: If I had believed he would know even one chapter or even one halakha I would not have been so harsh. He said to him: I am he. Ben Kalba Savua fell on his face and kissed his feet and gave him half of his money. The Gemara relates: Rabbi Akiva’s daughter did the same thing for ben Azzai, who was also a simple person, and she caused him to learn Torah in a similar way, by betrothing herself to him and sending him off to study. This explains the folk saying that people say: The ewe follows the ewe; the daughter’s actions are the same as her mother’s.

(6) One who, by vow, interdicts his wife from intercourse, Beit Shammai say, [she must wait] two weeks. Beit Hillel say one week. Students who leave for the purpose of studying Torah without the consent of their wives [have] thirty days; laborers, one week. [The law of providing sexual] pleasure [to one's wife] that is stated in the Torah [is as follows]: one at leisure, daily; laborers, twice a week; donkey drivers, once a week; camel drivers, once every thirty days; navigators every six months; these are the words of Rabbi Eliezer.

Ben Kalba Savua was called this because anyone who entered his house when he was hungry as a dog [kelev] would leave satiated [save’a].

(33) (Ibid. 7) "And Moses was one hundred and twenty years old when he died": He was one of the four who died at the age of one hundred and twenty: Moses, Hillel the Elder, R. Yochanan b. Zakkai, and R. Akiva. Moses was in Egypt for forty years, in Midian for forty years, and led Israel for forty years. Hillel the Elder went up from Bavel (to Eretz Yisrael) at the age of forty, attended upon the sages for forty years, and led Israel for forty years. R. Yochanan b. Zakkai was in business for forty years, attended upon the sages for forty years, and led Israel for forty years. R. Akiva was a shepherd for forty years, learned (Torah) for forty years, and led Israel for forty years. Six "pairs" whose years (of life) were the same: Rivka and Kehoth; Levi and Amram; Joseph and Joshua; Samuel and Solomon; Moses and Hillel the Elder; R. Yochanan b. Zakkai and R. Akiva.

(13) Rabbi Akiva says: Joking and lightheartedness acclimate toward promiscuity. Tradition is a safeguarding fence around Torah. Tithes are a safeguarding fence around wealth. Vows are a safeguarding fence around abstinence. A safeguarding fence around wisdom is silence.

(14) He would say: Beloved is man, since he is created in the image [of God]. A deeper love - it is revealed to him that he is created in the image, as it says (Genesis 9:6): "for in God's image He made man." Beloved are Israel, since they are called children of the Omnipresent. A deeper love - it is revealed to them that they are called children to God, as it says (Deuteronomy 14:1): "You are children of the Lord, your God." Beloved are Israel, since a precious instrument has been given to them. A deeper love - it is revealed to them that the precious instrument with which the world was created has been given to them, as it says (Proverbs 4:2): "For a good lesson I have given to you; do not forsake my teaching."

(15) Everything is foreseen, and freewill is given, and with goodness the world is judged. And all is in accordance to the majority of the deed.

(16) He would say: Everything is given as collateral, and a net is cast over all of life. The shop is open, and the shopkeeper grants credit, and the accounting ledger is open, and the hand writes, and everyone who wants to borrow can come and borrow, and the collectors go constantly on their daily rounds and exact payment from man - with his knowledge or without his knowledge - and they have that upon which to rely, and the judgement is true judgement, and everything is prepared for the feast.

What was Rabbi Akiva like? - A worker who goes out with his basket. He finds wheat - he puts it in, barley - he puts it in, spelt - he puts it in, beans - he puts it in, lentils - he puts it in. When he arrives home he sorts out the wheat by itself, barley by itself, spelt by itself, beans by themselves, lentils by themselves. So did Rabbi Akiva; he arranged the Torah rings by rings.

(8) Rabban Gamliel had, on a tablet, and on the walls of his loft, various drawings of the moon, which he showed to simple witnesses, and said, "Was it like this [drawing] that you saw, or like [the other one]?" It happened once, that two witnesses came and said, "We saw [the moon] in the East in the morning, and in the evening in the West." [In that case,] Rabbi Yochanan ben Nuri said, "They are false witnesses." [But] when they came to Yavneh, Rabban Gamliel accepted [their testimony. It] also [happened once that] two witnesses came and said, "We saw the moon at its time [meaning, on the first of the two possible days], but it was not [to be] seen [afterwards] on the evening of its intercalation," and Rabban Gamliel accepted [their testimony]. Rabbi Dosa ben Harkinus said, "They are false witnesses; how can they testify that a [certain] woman gave birth [on a certain day], and, on the next day that her 'womb was between her teeth' [and the fetus still inside]?" [Then] Rabbi Yehoshua said to him, "I perceive [the truth of] your words."

(9) [Upon hearing this,] Rabban Gamliel sent [Rabbi Yehoshua] word, saving, "I decree upon you to come to me with your staff and your money on the day that comes out to be Yom Kippur, according to your calculation." Rabbi Akiva went to [Rabbi Yehoshua], and found him grieving; he said to him, "I have with what to teach, that all that Rabban Gamliel has done is [bindingly] done, as it is stated (Leveticus 23:4), 'These are the feasts of the Lord, holy convocations which you shall proclaim;' whether at their [proper] time, or whether not at their [proper] time, I have no holy convocations except [for the ones proclaimed by the court." When Rabbi Yehoshua] came to Rabbi Dosa ben Harkinus, [the latter] said to him, "If we are to [question the decisions] of the court of Rabban Gamliel, we must [also question the decisions] of all the courts which have stood, from the days of Moshe until [today]; as it is stated, (Exodus 24:2), 'Moshe, Aharon, Nadav, Avihu, and seventy of the elders of Israel went up.' Why were the names of the elders not specified? Rather [it was] to teach, that every three men that form ‏a court [to be responsible] over Israel, behold [that court] is to be [considered] like the court of Moshe." [After this], Rabbi Yehoshua took his staff and his money in his hand, and went to Yavneh to Rabban Gamliel on the day that came out to be Yom Kippur, according to his calculation. [At that point], Rabban Gamliel stood up, and kissed him on his head, [and] he said to him, "Come in peace, my teacher and my disciple! My teacher — in wisdom; and my disciple — in that you accepted my words."

We learned in the mishna: The evening prayer may be recited throughout the night and is not fixed to a specific hour. The Gemara asks: What is the meaning of is not fixed? If you say that if one wishes, he may pray throughout the night, then let the mishna teach: The evening prayer may be recited throughout the night. Rather, what is the meaning of not fixed? It is in accordance with the opinion of the one who said: The evening prayer is optional. As Rav Yehuda said that Shmuel said with regard to the evening prayer. Rabban Gamliel says: It is obligatory. Rabbi Yehoshua says: It is optional. Abaye said: The halakha is in accordance with the statement of the one who said: The evening prayer is obligatory. Rava said: The halakha is in accordance with the statement of the one who said: The evening prayer is optional. The Sages taught: There was an incident involving a student, who came before Rabbi Yehoshua. The student said to him: Is the evening prayer optional or obligatory? Rabbi Yehoshua said to him: Optional. The same student came before Rabban Gamliel and said to him: Is the evening prayer optional or obligatory? Rabban Gamliel said to him: Obligatory. The student said to Rabban Gamliel: But didn’t Rabbi Yehoshua tell me that the evening prayer is optional? Rabban Gamliel said to the student: Wait until the “masters of the shields,” a reference to the Torah scholars who battle in the war of Torah, enter the study hall, at which point we will discuss this issue. When the masters of the shields entered, the questioner stood before everyone present and asked: Is the evening prayer optional or obligatory? Rabban Gamliel said to him: Obligatory. In order to ascertain whether or not Rabbi Yehoshua still maintained his opinion, Rabban Gamliel said to the Sages: Is there any person who disputes this matter? Rabbi Yehoshua said to him: No, no one disagrees. In deference to the Nasi, he did not wish to argue with him publicly (Tziyyun LeNefesh Ḥayya). Rabban Gamliel said to Rabbi Yehoshua: But was it not in your name that they told me that the evening prayer is optional? Rabban Gamliel said to Rabbi Yehoshua: Yehoshua, stand on your feet and they will testify against you. Rabbi Yehoshua stood on his feet and said: If I were alive and the student were dead, the living can contradict the dead, and I could deny issuing that ruling. Now that I am alive and he is alive, how can the living contradict the living? I have no choice but to admit that I said it. In the meantime, Rabban Gamliel, as the Nasi, was sitting and lecturing, and Rabbi Yehoshua all the while was standing on his feet, because Rabban Gamliel did not instruct him to sit. He remained standing in deference to the Nasi. This continued for some time, until it aroused great resentment against Rabban Gamliel, and all of the people assembled began murmuring and said to Ḥutzpit the disseminator: Stop conveying Rabban Gamliel’s lecture. And he stopped. The Gemara relates that in their murmuring they said: How long will Rabban Gamliel continue afflicting him? Last year on Rosh HaShana, he afflicted him; Rabban Gamliel ordered Rabbi Yehoshua to come to him carrying his staff and bag, on the day on which Yom Kippur occurred, according to Rabbi Yehoshua’s calculations. Regarding the firstborn, in the incident involving the question of Rabbi Tzadok, he afflicted him just as he did now, and forced him to remain standing as punishment for his failure to defend his differing opinion. Here too, he is afflicting him. Let us remove him from his position as Nasi. It was so agreed, but the question arose: Who shall we establish in his place? Shall we establish Rabbi Yehoshua in his place? The Sages rejected that option because Rabbi Yehoshua was party to the incident for which Rabban Gamliel was deposed. Appointing him would be extremely upsetting for Rabban Gamliel. Shall we establish Rabbi Akiva in his place? The Sages rejected that option because Rabbi Akiva, who descended from a family of converts, would be vulnerable. Perhaps due to Rabban Gamliel’s resentment he would cause him to be divinely punished as he lacks the merit of his ancestors to protect him. Rather, suggested the Sages, let us establish Rabbi Elazar ben Azarya in his place, his outstanding characteristics set him apart from the other candidates. He is wise, rich, and a tenth generation descendant of Ezra. The Gemara explains: He is wise, so if Rabban Gamliel raises a challenge in matters of Torah, he will answer it and not be embarrassed. And he is rich, so if the need arises to pay homage to the Caesar’s court and serve as a representative of Israel to lobby and negotiate, he has sufficient wealth to cover the costs of the long journeys, taxes, and gifts, so he too is able to go and pay homage. And he is a tenth generation descendant of Ezra, so he has the merit of his ancestors, and Rabban Gamliel will be unable to cause him to be punished. They came and said to him: Would the Master consent to being the Head of the Yeshiva? He said to them: I will go and consult with my household. He went and consulted with his wife. She said to him:

And this is known as the oven of akhnai. The Gemara asks: What is the relevance of akhnai, a snake, in this context? Rav Yehuda said that Shmuel said: It is characterized in that manner due to the fact that the Rabbis surrounded it with their statements like this snake, which often forms a coil when at rest, and deemed it impure. The Sages taught: On that day, when they discussed this matter, Rabbi Eliezer answered all possible answers in the world to support his opinion, but the Rabbis did not accept his explanations from him. After failing to convince the Rabbis logically, Rabbi Eliezer said to them: If the halakha is in accordance with my opinion, this carob tree will prove it. The carob tree was uprooted from its place one hundred cubits, and some say four hundred cubits. The Rabbis said to him: One does not cite halakhic proof from the carob tree. Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, the stream will prove it. The water in the stream turned backward and began flowing in the opposite direction. They said to him: One does not cite halakhic proof from a stream. Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, the walls of the study hall will prove it. The walls of the study hall leaned inward and began to fall. Rabbi Yehoshua scolded the walls and said to them: If Torah scholars are contending with each other in matters of halakha, what is the nature of your involvement in this dispute? The Gemara relates: The walls did not fall because of the deference due Rabbi Yehoshua, but they did not straighten because of the deference due Rabbi Eliezer, and they still remain leaning. Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, Heaven will prove it. A Divine Voice emerged from Heaven and said: Why are you differing with Rabbi Eliezer, as the halakha is in accordance with his opinion in every place that he expresses an opinion? Rabbi Yehoshua stood on his feet and said: It is written: “It is not in heaven” (Deuteronomy 30:12). The Gemara asks: What is the relevance of the phrase “It is not in heaven” in this context? Rabbi Yirmeya says: Since the Torah was already given at Mount Sinai, we do not regard a Divine Voice, as You already wrote at Mount Sinai, in the Torah: “After a majority to incline” (Exodus 23:2). Since the majority of Rabbis disagreed with Rabbi Eliezer’s opinion, the halakha is not ruled in accordance with his opinion. The Gemara relates: Years after, Rabbi Natan encountered Elijah the prophet and said to him: What did the Holy One, Blessed be He, do at that time, when Rabbi Yehoshua issued his declaration? Elijah said to him: The Holy One, Blessed be He, smiled and said: My children have triumphed over Me; My children have triumphed over Me. The Sages said: On that day, the Sages brought all the ritually pure items deemed pure by the ruling of Rabbi Eliezer with regard to the oven and burned them in fire, and the Sages reached a consensus in his regard and ostracized him. And the Sages said: Who will go and inform him of his ostracism? Rabbi Akiva, his beloved disciple, said to them: I will go, lest an unseemly person go and inform him in a callous and offensive manner, and he would thereby destroy the entire world. What did Rabbi Akiva do? He wore black and wrapped himself in black, as an expression of mourning and pain, and sat before Rabbi Eliezer at a distance of four cubits, which is the distance that one must maintain from an ostracized individual. Rabbi Eliezer said to him: Akiva, what is different about today from other days, that you comport yourself in this manner? Rabbi Akiva said to him: My teacher, it appears to me that your colleagues are distancing themselves from you. He employed euphemism, as actually they distanced Rabbi Eliezer from them. Rabbi Eliezer too, rent his garments and removed his shoes, as is the custom of an ostracized person, and he dropped from his seat and sat upon the ground. The Gemara relates: His eyes shed tears, and as a result the entire world was afflicted: One-third of its olives were afflicted, and one-third of its wheat, and one-third of its barley. And some say that even dough kneaded in a woman’s hands spoiled. The Sages taught: There was great anger on that day, as any place that Rabbi Eliezer fixed his gaze was burned. And even Rabban Gamliel, the Nasi of the Sanhedrin at Yavne, the head of the Sages who were responsible for the decision to ostracize Rabbi Eliezer, was coming on a boat at the time, and a large wave swelled over him and threatened to drown him. Rabban Gamliel said: It seems to me that this is only for the sake of Rabbi Eliezer ben Hyrcanus, as God punishes those who mistreat others. Rabban Gamliel stood on his feet and said: Master of the Universe, it is revealed and known before You that neither was it for my honor that I acted when ostracizing him, nor was it for the honor of the house of my father that I acted; rather, it was for Your honor, so that disputes will not proliferate in Israel. In response, the sea calmed from its raging. The Gemara further relates: Imma Shalom, the wife of Rabbi Eliezer, was the sister of Rabban Gamliel. From that incident forward, she would not allow Rabbi Eliezer to lower his head and recite the taḥanun prayer, which includes supplication and entreaties. She feared that were her husband to bemoan his fate and pray at that moment, her brother would be punished. A certain day was around the day of the New Moon, and she inadvertently substituted a full thirty-day month for a deficient twenty-nine-day month, i.e., she thought that it was the New Moon, when one does not lower his head in supplication, but it was not. Some say that a pauper came and stood at the door, and she took bread out to him. The result was that she left her husband momentarily unsupervised. When she returned, she found him and saw that he had lowered his head in prayer. She said to him: Arise, you already killed my brother. Meanwhile, the sound of a shofar emerged from the house of Rabban Gamliel to announce that the Nasi had died. Rabbi Eliezer said to her: From where did you know that your brother would die? She said to him: This is the tradition that I received from the house of the father of my father: All the gates of Heaven are apt to be locked, except for the gates of prayer for victims of verbal mistreatment. §

(1) Rabbi Eliezer says: If one has not brought an instrument [knife used for circumcision] on Shabbat eve [Friday] he may bring it uncovered on Shabbat; but in times of danger [religious persecution] he may cover [the knife by wrapping it up] in the presence of witnesses. And Rabbi Eliezer further said: One may cut wood [on Shabbat] to make coal in order to forge the iron instrument [for circumcision]. Rabbi Akiva stated a principle: [If] a Melakhah [a constructive activity forbidden on Shabbat and festivals] could have been done on Shabbat eve [Friday] its [performance] does not override Shabbat; but [if] it could not have been done on Shabbat eve it does override Shabbat.

Rav Yehuda says that Rav says: When Moses ascended on High, he found the Holy One, Blessed be He, sitting and tying crowns on the letters of the Torah. Moses said before God: Master of the Universe, who is preventing You from giving the Torah without these additions? God said to him: There is a man who is destined to be born after several generations, and Akiva ben Yosef is his name; he is destined to derive from each and every thorn of these crowns mounds upon mounds of halakhot. It is for his sake that the crowns must be added to the letters of the Torah. Moses said before God: Master of the Universe, show him to me. God said to him: Return behind you. Moses went and sat at the end of the eighth row in Rabbi Akiva’s study hall and did not understand what they were saying. Moses’ strength waned, as he thought his Torah knowledge was deficient. When Rabbi Akiva arrived at the discussion of one matter, his students said to him: My teacher, from where do you derive this? Rabbi Akiva said to them: It is a halakha transmitted to Moses from Sinai. When Moses heard this, his mind was put at ease, as this too was part of the Torah that he was to receive. Moses returned and came before the Holy One, Blessed be He, and said before Him: Master of the Universe, You have a man as great as this and yet You still choose to give the Torah through me. Why? God said to him: Be silent; this intention arose before Me. Moses said before God: Master of the Universe, You have shown me Rabbi Akiva’s Torah, now show me his reward. God said to him: Return to where you were. Moses went back and saw that they were weighing Rabbi Akiva’s flesh in a butcher shop [bemakkulin], as Rabbi Akiva was tortured to death by the Romans. Moses said before Him: Master of the Universe, this is Torah and this is its reward? God said to him: Be silent; this intention arose before Me. §

“Baraita of R. Ishmael”: The Thirteen Rules

The thirteen rules were compiled by Rabbi Ishmael b. Elisha for the elucidation of the Torah and for making halakhic deductions from it. They are, strictly speaking, mere amplifications of the seven Rules of Hillel, and are collected in the “Baraita of R. Ishmael,” forming the introduction to the Sifra and reading as follows:

1. Kal va-chomer: “Simple and complex, complex and simple.” Deductions are made from the simple to the complex or vice versa, according to the nature of the conclusion required. Identical with the first rule of Hillel.

2. Gezerah shavah: “Similar laws, similar verdicts.” An argument by analogy, which infers from the similarity of two cases that the legal decision given for the one also holds good for the other. Identical with the second rule of Hillel.

3. Binyan ab: “A standard from a passage/passages of Scripture.” A certain passage serves as a basis for the interpretation of many others so that the decision given in the case of one is valid for all the rest, or a decision in two laws having a characteristic in common is applied to many other laws which have this same characteristic. This rule is a combination of the third and fourth rules of Hillel.

4. Kelal u-perat: “General and particular, particular and general” is a limitation of the general by the particular and vice versa.

5. U-perat. u-kelal: The particular and the general.

6. Kelal u-perat. u-kelal: The general, the particular, and the general.

7. The general which requires elucidation by the particular, and the particular which requires elucidation by

   the general.

8. The particular implied in the general and excepted from it for pedagogic purposes elucidates the general

   as well as the particular.

9. The particular implied in the general and excepted from it on account of the special regulation which

   corresponds in concept to the general, is thus isolated to decrease rather than to increase the rigidity of its

   application.

10. The particular implied in the general and excepted from it on account of some other special regulation

    which does not correspond in concept to the general, is thus isolated either to decrease or to increase the

    rigidity of its application.

11. The particular implied in the general and excepted from it on account of a new and reversed decision can

    be referred to the general only in case the passage under consideration makes an explicit reference to it.

12. Deduction from the context.

13. When two biblical passages contradict each other the contradiction in question must be solved by

    reference to a third passage.

(5) A book [i.e. a Torah scroll] which was erased leaving only eighty-five letters in it, like the portion of (Numbers 10:35-36), "And it was when the Ark was raised...,"‏ renders the hands impure. A scroll on which are written eighty-five letters, like the portion of, "And it was when the Ark was raised...,"‏ renders the hands impure. All sacred scriptures render the hands impure. The Song of Songs and Ecclesiastes render the hands impure. Rabbi Yehudah says: The Song of Songs renders the hands impure, but there is a dispute regarding Ecclesiastes. Rabbi Yose says: Ecclesiastes does not render the hands impure, and there is a dispute regarding The Song of Songs. Rabbi Shimon says: Ecclesiastes is among the [relative] leniencies of Beit Shammai, and the [relative] stringencies of Beit Hillel. Rabbi Shimon ben Azzai said, "I have a recieved tradition from the mouths of seventy-two elders, on the day they inducted Rabbi Elazar ben Azaria into his seat [as head] at the Academy, that The Song of Songs and Ecclesiastes render the hands impure." Rabbi Akiva said, "Mercy forbid! No one in Israel ever disputed that The Song of Songs renders the hands impure, since nothing in the entire world is worthy but for that day on which The Song of Songs was given to Israel; for all the Scriptures are holy, but The Song of Songs is the Holy of Holies! And if they did dispute, there was only a dispute regarding Ecclesiastes." Rabbi Yochanan ben Yehoshua, the son of Rabbi Akiva's father-in-law, said, "In accordance with words of Ben Azzai, thus did they dispute, and thus did they conclude."

(1) One may not expound the laws of forbidden sexual relations before three people, nor the account of Creation before two, nor the Divine Chariot before one, unless he is wise and understanding from his own knowledge. Anyone who looks into four things would be better off if he had not come into this world: what is above, what is below, what is before, and what is after. And anyone who has no consideration for the honor of his Maker would be better off if he had not come into the world.

Rabbi Shimon Bar Yochai said: My teacher, Rabbi Akiva, would expound on the verse "A Star has risen from Jacob." When Rabbi Akiva would see Bar Kusba (Bar Kochba) he would say, 'that is the King the Messiah.' Rabbi Yochanan ben Torta said to him: Akiva! Grass will grow on your cheeks and the son of David will not yet have come!

Rabbi Akiva says that the verse should be understood as follows: If one studied Torah in his youth he should study more Torah in his old age; if he had students in his youth he should have additional students in his old age, as it is stated: “In the morning sow your seed, etc.” They said by way of example that Rabbi Akiva had twelve thousand pairs of students in an area of land that stretched from Gevat to Antipatris in Judea, and they all died in one period of time, because they did not treat each other with respect. And the world was desolate of Torah until Rabbi Akiva came to our Rabbis in the South and taught his Torah to them. This second group of disciples consisted of Rabbi Meir, Rabbi Yehuda, Rabbi Yosei, Rabbi Shimon, and Rabbi Elazar ben Shamua. And these are the very ones who upheld the study of Torah at that time. Although Rabbi Akiva’s earlier students did not survive, his later disciples were able to transmit the Torah to future generations. With regard to the twelve thousand pairs of Rabbi Akiva’s students, the Gemara adds: It is taught that all of them died in the period from Passover until Shavuot. Rav Ḥama bar Abba said, and some say it was Rabbi Ḥiyya bar Avin: They all died a bad death. The Gemara inquires: What is it that is called a bad death? Rav Naḥman said: Diphtheria.

Rabbi Akiva had twelve thousand pairs of disciples from Akko to Antiparos and all of them died at the same period of time. Why? Because their eyes were narrow with one another. Eventually Rabbi Akiva raised seven disciples: R. Meir, R. Yehudah, R. Yose, R. Shimon, R. Eleazar b. Shammua, R. Yohanan the Cobbler, and R. Eliezer b. Jacob...Rabbi Akiva said: My first sons died only because their eyes were narrow with each other in Torah. See to it that you do not do as they did. They arose and filled all the land of Israel with Torah. (Holtz, p. 157)

(1) It is customary not to get married between Pesach and Shavuot, until Lag BaOmer (the 33rd day), because during that time, the students of Rabbi Akiva died. However, to do "erusin" and "kiddushin" (engagement and betrothal) is OK. And even for "nisuin" (marriage), if someone did so, we do not punish him. Rema: however, from Lag Ba'Omer onwards, all this is permitted (Abudraham, Beit Yosef & Minhagim).

(2) It is customary not to cut one's hair until Lag BaOmer, since it is said that that is when they stopped dying.

(5) A person is obligated to bless upon the bad just as he blesses upon the good. As it says, “And you shall love the Lord your God, with all your heart and all your soul and with all that you have.” (Deut. 6:5) “With all your heart” – with your two inclinations, with the inclination of good and the inclination of evil. “And in all your soul” – even if He takes your soul. “And with all that you have” – with all your money. Alternatively, “With all that you have” – with every measure that is measured for you thank Him very much.

Rabbi Akiva says: “With all your soul” means: Even if God takes your soul. The Gemara relates at length how Rabbi Akiva fulfilled these directives. The Sages taught: One time, after the bar Kokheva rebellion, the evil empire of Rome decreed that Israel may not engage in the study and practice of Torah. Pappos ben Yehuda came and found Rabbi Akiva, who was convening assemblies in public and engaging in Torah study. Pappos said to him: Akiva, are you not afraid of the empire? Rabbi Akiva answered him: I will relate a parable. To what can this be compared? It is like a fox walking along a riverbank when he sees fish gathering and fleeing from place to place.
The fox said to them: From what are you fleeing?
They said to him: We are fleeing from the nets that people cast upon us.
He said to them: Do you wish to come up onto dry land, and we will reside together just as my ancestors resided with your ancestors?
The fish said to him: You are the one of whom they say, he is the cleverest of animals? You are not clever; you are a fool. If we are afraid in the water, our natural habitat which gives us life, then in a habitat that causes our death, all the more so.
The moral is: So too, we Jews, now that we sit and engage in Torah study, about which it is written: “For that is your life, and the length of your days” (Deuteronomy 30:20), we fear the empire to this extent; if we proceed to sit idle from its study, as its abandonment is the habitat that causes our death, all the more so will we fear the empire. The Sages said: Not a few days passed until they seized Rabbi Akiva and incarcerated him in prison, and seized Pappos ben Yehuda and incarcerated him alongside him. Rabbi Akiva said to him: Pappos, who brought you here? Pappos replied: Happy are you, Rabbi Akiva, for you were arrested on the charge of engaging in Torah study. Woe unto Pappos who was seized on the charge of engaging in idle matters. The Gemara relates: When they took Rabbi Akiva out to be executed, it was time for the recitation of Shema. And they were raking his flesh with iron combs, and he was reciting Shema, thereby accepting upon himself the yoke of Heaven. His students said to him: Our teacher, even now, as you suffer, you recite Shema? He said to them: All my days I have been troubled by the verse: With all your soul, meaning: Even if God takes your soul. I said to myself: When will the opportunity be afforded me to fulfill this verse? Now that it has been afforded me, shall I not fulfill it? He prolonged his uttering of the word: One, until his soul left his body as he uttered his final word: One. A voice descended from heaven and said: Happy are you, Rabbi Akiva, that your soul left your body as you uttered: One. The ministering angels said before the Holy One, Blessed be He: This is Torah and this its reward? As it is stated: “From death, by Your hand, O Lord, from death of the world” (Psalms 17:14); Your hand, God, kills and does not save. God said the end of the verse to the ministering angels: “Whose portion is in this life.” And then a Divine Voice emerged and said: Happy are you, Rabbi Akiva, as you are destined for life in the World-to-Come, as your portion is already in eternal life.

..."The sun rises and goes down" (Ecclesiastics 1:5). Rabbi Aba bar Kahana said: Don't we know that the sun rises and goes down? Rather (this is what it means): When the Holy One of Blessing causes the sun of a righteous person to set, he causes the sun of his fellow to shine forth. The day that Rabbi Akiba died, our rabbi (Judah the Prince) was born and it was written about him "The sun rises and the sun goes down."

“And your brother shall live with you” (Leviticus 25:36), from which it is derived: Return the interest to him so that he may live. The Gemara asks: And Rabbi Yoḥanan, what does he do with this verse: “And your brother shall live with you”? The Gemara answers: He requires the verse for that which is taught in a baraita: If two people were walking on a desolate path and there was a jug [kiton] of water in the possession of one of them, and the situation was such that if both drink from the jug, both will die, as there is not enough water, but if only one of them drinks, he will reach a settled area, there is a dispute as to the halakha. Ben Petora taught: It is preferable that both of them drink and die, and let neither one of them see the death of the other. This was the accepted opinion until Rabbi Akiva came and taught that the verse states: “And your brother shall live with you,” indicating that your life takes precedence over the life of the other.

(5) A book [i.e. a Torah scroll] which was erased leaving only eighty-five letters in it, like the portion of (Numbers 10:35-36), "And it was when the Ark was raised...,"‏ renders the hands impure. A scroll on which are written eighty-five letters, like the portion of, "And it was when the Ark was raised...,"‏ renders the hands impure. All sacred scriptures render the hands impure. The Song of Songs and Ecclesiastes render the hands impure. Rabbi Yehudah says: The Song of Songs renders the hands impure, but there is a dispute regarding Ecclesiastes. Rabbi Yose says: Ecclesiastes does not render the hands impure, and there is a dispute regarding The Song of Songs. Rabbi Shimon says: Ecclesiastes is among the [relative] leniencies of Beit Shammai, and the [relative] stringencies of Beit Hillel. Rabbi Shimon ben Azzai said, "I have a recieved tradition from the mouths of seventy-two elders, on the day they inducted Rabbi Elazar ben Azaria into his seat [as head] at the Academy, that The Song of Songs and Ecclesiastes render the hands impure." Rabbi Akiva said, "Mercy forbid! No one in Israel ever disputed that The Song of Songs renders the hands impure, since nothing in the entire world is worthy but for that day on which The Song of Songs was given to Israel; for all the Scriptures are holy, but The Song of Songs is the Holy of Holies! And if they did dispute, there was only a dispute regarding Ecclesiastes." Rabbi Yochanan ben Yehoshua, the son of Rabbi Akiva's father-in-law, said, "In accordance with words of Ben Azzai, thus did they dispute, and thus did they conclude."

(1) Let our rabbis teach us: one who passes before the ark [i.e., serves as precentor for the 'amidah] and errs by not mentioning the birkat haminim--from whence do we know that we make him repeat the prayer? That is what the rabbis taught: One who passes before the ark and errs in any or all of the blessings, we do not make him repeat the prayer. But if he errs in the birkat haminim, we make him repeat and recite it against his will. And why do we make him repeat it? We are concerned lest he is a min, for if he has some aspect of minut, he will curse himself and the congregation will answer "amen."

Late Tannaitic - Minor Tractate

This story of Rabbi Akiva's encounter with the soul of a sinner appears in many versions including the one below (not exact translation of the Hebrew text).

"The French halakhic work Mahzor Vitry (12th century) via this story, links this notion, (i.e., that the living can do good for the dead) with the Kaddish." - Alyssa Gray, My People's Prayer Book, Vol.6, p 157.

See codification of this below - ReMA on Shulhan Arukh Yoreh Deah 376:4.

Rabbi Akiva once saw a man struggling with a heavy burden on his shoulders and bemoaning his lot in life. Rabbi Akiva asked the man what his story was. The oppressed laborer replied that he was the soul of a person who committed every conceivable sin and that if he stopped to talk, he’d get in even more trouble.

The punishment of this particular sinner was to gather wood, which was used to burn him every day. Rabbi Akiva asked if there was any way to free this soul and the deceased replied that the only way was if he had a son who would stand in front of the congregation and say “Barchu es Hashem hamevorah” or “Yisgadal v’yiskadash…,” after which the congregation would reply, “Baruch Hashem hamevorah l’olam voed” or “Yehei shmei rabbah…,” respectively. (These are the prayers of Barchu and Kaddish, in which the leader of the service calls upon the congregation to praise God, which they then do.)

Finally, Rabbi Akiva asked the man who had survived him; the spirit replied that his wife had been pregnant when he died. Rabbi Akiva recorded the name of the deceased, the man’s wife, and his hometown so that he might investigate the matter.

Hurrying to the man’s city, Rabbi Akiva discovered that the deceased was particularly reviled by the townspeople. He had been a corrupt tax collector who took bribes from the rich and oppressed the poor. Among his more notorious deeds, the man had violated a betrothed girl on Yom Kippur! Rabbi Akiva located the widow, who had given birth to a son. So despised was her husband that no one had even circumcised the child. Rabbi Akiva took care of this grievous omission and, when the child was old enough, he taught him Torah and how to daven in shul, including the prayers the man had specified.

As soon as the boy recited the appropriate prayers, his father’s soul was relieved of its harsh punishments. The man’s spirit re-appeared to Rabbi Akiva in a dream to thank the scholar for saving him from the tortures of Gehinnom.
