Put your hand under my thigh??

(ב) וַיֹּ֣אמֶר אַבְרָהָ֗ם אֶל־עַבְדּוֹ֙ זְקַ֣ן בֵּית֔וֹ הַמֹּשֵׁ֖ל בְּכָל־אֲשֶׁר־ל֑וֹ שִֽׂים־נָ֥א יָדְךָ֖ תַּ֥חַת יְרֵכִֽי׃ (ג) וְאַשְׁבִּ֣יעֲךָ֔ בַּֽה' אֱלֹהֵ֣י הַשָּׁמַ֔יִם וֵֽאלֹהֵ֖י הָאָ֑רֶץ אֲשֶׁ֨ר לֹֽא־תִקַּ֤ח אִשָּׁה֙ לִבְנִ֔י מִבְּנוֹת֙ הַֽכְּנַעֲנִ֔י אֲשֶׁ֥ר אָנֹכִ֖י יוֹשֵׁ֥ב בְּקִרְבּֽוֹ׃

(2) And Abraham said unto his servant, the elder of his house, that ruled over all that he had: ‘Put, I pray thee, thy hand under my thigh. (3) And I will make thee swear by the LORD, the God of heaven and the God of the earth, that thou shalt not take a wife for my son of the daughters of the Canaanites, among whom I dwell.

(כט) וַיִּקְרְב֣וּ יְמֵֽי־יִשְׂרָאֵ֘ל לָמוּת֒ וַיִּקְרָ֣א ׀ לִבְנ֣וֹ לְיוֹסֵ֗ף וַיֹּ֤אמֶר לוֹ֙ אִם־נָ֨א מָצָ֤אתִי חֵן֙ בְּעֵינֶ֔יךָ שִֽׂים־נָ֥א יָדְךָ֖ תַּ֣חַת יְרֵכִ֑י וְעָשִׂ֤יתָ עִמָּדִי֙ חֶ֣סֶד וֶאֱמֶ֔ת אַל־נָ֥א תִקְבְּרֵ֖נִי בְּמִצְרָֽיִם׃ (ל) וְשָֽׁכַבְתִּי֙ עִם־אֲבֹתַ֔י וּנְשָׂאתַ֙נִי֙ מִמִּצְרַ֔יִם וּקְבַרְתַּ֖נִי בִּקְבֻרָתָ֑ם וַיֹּאמַ֕ר אָנֹכִ֖י אֶֽעֱשֶׂ֥ה כִדְבָרֶֽךָ׃ (לא) וַיֹּ֗אמֶר הִשָּֽׁבְעָה֙ לִ֔י וַיִּשָּׁבַ֖ע ל֑וֹ וַיִּשְׁתַּ֥חוּ יִשְׂרָאֵ֖ל עַל־רֹ֥אשׁ הַמִּטָּֽה׃ (פ)

(29) And the time drew near that Israel must die; and he called his son Joseph, and said unto him: ‘If now I have found favour in thy sight, put, I pray thee, thy hand under my thigh, and deal kindly and truly with me; bury me not, I pray thee, in Egypt. (30) But when I sleep with my fathers, thou shalt carry me out of Egypt, and bury me in their burying-place.’ And he said: ‘I will do as thou hast said.’ (31) And he said: ‘Swear unto me.’ And he swore unto him. And Israel bowed down upon the bed’s head.

(48) And Laban said: ‘This heap is witness between me and thee this day.’ Therefore was the name of it called Galeed; (49) and Mizpah, for he said: ‘The LORD watch between me and thee, when we are absent one from another. (50) If thou shalt afflict my daughters, and if thou shalt take wives beside my daughters, no man being with us; see, God is witness betwixt me and thee.’ (51) And Laban said to Jacob: ‘Behold this heap, and behold the pillar, which I have set up betwixt me and thee. (52) This heap be witness, and the pillar be witness, that I will not pass over this heap to thee, and that thou shalt not pass over this heap and this pillar unto me, for harm. (53) The God of Abraham, and the God of Nahor, the God of their father, judge betwixt us.’ And Jacob swore by the Fear of his father Isaac.

Questions:

1) What is similar about the circumstances of each of these oaths?

2) What do you think is the symbolic meaning of holding the sexual organs while swearing an oath?

2) Traditional Rabbinic understanding of this oath

(א) זקן ביתו. לפי שהוא דבוק נקוד זקן:

(ב) תחת ירכי. לפי שהנשבע צריך שיטול בידו חפץ של מצוה, כגון ספר תורה או תפלין, והמילה היתה מצוה ראשונה לו ובאה לו על ידי צער והיתה חביבה עליו ונטלה:

(1) under my thigh: (Shev. 38) Since one who swears must take with his hand an article related to a mitzvah such as a Torah scroll or Tefillin, and circumcision was his first mitzvah, and he had fulfilled it with pain, it was dear to him; so he took it.

3) The oath gesture as used in concurrent Near Eastern societies

Babylonian Letter from the city Kissura in South Mesopotamia: Translated from cuneiform

"Thus you (have said to me): 'Let your envoy grasp my testicles and my penis and then I will give (it) to you'. Concerning (?) then what you have said to me, (I am dispatching to you) Burriya the son of Menanum"

Questions:

1) How does the appearance of this letter challenge Rashi's interpretation?

2) How is the oath as sworn in the Babylonian letter different from those sworn in Sefer Bereishit?

3) Given that this letter at least challenges the idea of an explicit reference to circumcision in the oath, what else might this oath gesture be invoking?

4) Meir Malul on the Oath by the Thigh

"Touching the procreative organ while promising to maintain the cohesion of the family must have entailed invoking the ancestral spirits of the family to witness and assure the fulfillment of the promise. Failure to keep it or an attempt to violate the principle of the family cohesion would arouse the wrath of the ancestral spirits"

"It is the purity and continuity of the family, conceived as an entity existing and significant throughout time, both within and beyond the confines of life on earth, which are at stake in these last requests"

Perhaps it's this covenant that was being invoked...

(ה) וַיּוֹצֵ֨א אֹת֜וֹ הַח֗וּצָה וַיֹּ֙אמֶר֙ הַבֶּט־נָ֣א הַשָּׁמַ֗יְמָה וּסְפֹר֙ הַכּ֣וֹכָבִ֔ים אִם־תּוּכַ֖ל לִסְפֹּ֣ר אֹתָ֑ם וַיֹּ֣אמֶר ל֔וֹ כֹּ֥ה יִהְיֶ֖ה זַרְעֶֽךָ׃ (יח) בַּיּ֣וֹם הַה֗וּא כָּרַ֧ת ה' אֶת־אַבְרָ֖ם בְּרִ֣ית לֵאמֹ֑ר לְזַרְעֲךָ֗ נָתַ֙תִּי֙ אֶת־הָאָ֣רֶץ הַזֹּ֔את מִנְּהַ֣ר מִצְרַ֔יִם עַד־הַנָּהָ֥ר הַגָּדֹ֖ל נְהַר־פְּרָֽת׃

(5) And He brought him forth abroad, and said: ‘Look now toward heaven, and count the stars, if thou be able to count them’; and He said unto him: ‘So shall thy seed be.’ (18) In that day the LORD made a covenant with Abram, saying: ‘Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates;


1) The "double oath" of the oath by the thigh, simultaneously swearing by God and by ancestors,seems to be a powerful motivation for a person to follow through with the oath. So why do we stop using it after Bereishit?

(ו) וַיֹּ֗אמֶר אָנֹכִי֙ אֱלֹהֵ֣י אָבִ֔יךָ אֱלֹהֵ֧י אַבְרָהָ֛ם אֱלֹהֵ֥י יִצְחָ֖ק וֵאלֹהֵ֣י יַעֲקֹ֑ב וַיַּסְתֵּ֤ר מֹשֶׁה֙ פָּנָ֔יו כִּ֣י יָרֵ֔א מֵהַבִּ֖יט אֶל־הָאֱלֹהִֽים׃
(6) Moreover He said: ‘I am the God of thy father, the God of Abraham, the God of Isaac, and the God of Jacob.’ And Moses hid his face; for he was afraid to look upon God.
