(8) Rabban Yohanan ben Zakkai received [the oral tradition] from Hillel and Shammai.He used to say: if you have learned much Torah, do not claim credit for yourself, because for such a purpose were you created. Rabban Yohanan ben Zakkai had five disciples and they were these: Rabbi Eliezer ben Hyrcanus, Rabbi Joshua ben Hananiah, Rabbi Yose, the priest, Rabbi Shimon ben Nethaneel and Rabbi Eleazar ben Arach. He [Rabbi Johanan] used to list their outstanding virtues: Rabbi Eliezer ben Hyrcanus is a plastered cistern which loses not a drop; Rabbi Joshua ben Hananiah happy is the woman that gave birth to him; Rabbi Yose, the priest, is a pious man; Rabbi Simeon ben Nethaneel is one that fears sin, And Rabbi Eleazar ben Arach is like a spring that [ever] gathers force. He [Rabbi Yohanan] used to say: if all the sages of Israel were on one scale of the balance and Rabbi Eliezer ben Hyrcanus on the other scale, he would outweigh them all. Abba Shaul said in his name: if all the sages of Israel were on one scale of the balance, and Rabbi Eliezer ben Hyrcanus also with them, and Rabbi Eleazar ben Arach on the other scale, he would outweigh them all.

"happy is the one who gave birth to him": Rendered happy by good character traits is one who the whole world says about him, "happy is the one who gave birth to him." And some say, because she caused him to be a sage. For she would go out to all of the study halls in her town and say to them, "I request from you that you should seek mercy (pray) for this embryo that is in my innards, that he should be a sage." And from the day that he was born, she did not remove his crib from the study hall, so that only words of Torah would enter his ears.

Rabbi Ḥelbo said: The wine of Phrygia [Perugaita] and the water of the Deyomset deprived Israel of the ten lost tribes. Because the members of these tribes were attracted to the pleasures of wine and bathing and did not occupy themselves with Torah, they were lost to the Jewish people.

The Gemara relates that once Rabbi Elazar ben Arakh happened to come there, to Phrygia and Deyomset, and he was drawn after them, and his Torah learning was forgotten. When he returned, he stood to read from a Torah scroll and was supposed to read the verse: “This month shall be for you [haḥodesh hazeh lakhem]” (Exodus 12:2), but he had forgotten so much that he could barely remember how to read the Hebrew letters, and instead he read: Have their hearts become deaf [haḥeresh haya libbam], interchanging the similar letters reish for dalet, yod for zayin, and beit for khaf. The Sages prayed and asked for God to have mercy on him, and his learning was restored.
