Midrash su Genesi 29:35

(Ib. b) R. Jochauan in the name of R. Simon b. Jochai said: "Since the day the Holy One, praised be He! created the world there was no man who called the Holy One, praised be He! 'Lord' (Adon) until Abraham came and called him 'Lord,' for it is said (Gen. 15, 8.) And he said Lord God, whereby shall I know that I shall inherit it?" Rab said "Daniel also would not have been answered were it not for the sake of Abraham, for it is said (Dan. 9, 17.) And now listen, O our God! to the prayer of thy servant, for the sake of the Lord; — 'for Thy sake' he [Daniel] ought to have said? But [he prayed] for the sake of Abraham, who called you Lord." Again said R. Jochanan in the name of R. Simon b. Jochai: "Since the day when the Holy One, praised be He! created the world, there was no man who thanked the Holy One, praised be He! until Leah came and thanked Him, as it is said (Gen. 29, 35.) This lime will I thank the Lord." What is the meaning of being called Reuben? R. Elazar said: "Leah said, 'See the difference between my son and the son of my father-in-law (Esau); whereas my father-in-law's son sold his birthright to Jacob of his own accord, as it is written (Gen. 25, 33.) And he sold his right of first-horn unto Jacob, yet what happened? As it is written (Ib. 27, 41.) And Esau hated Jacob, and it is also written (Ib. ib. 36.) And he said, hath he been therefore named Jacob, because he hath supplanted me these two times; but my son, although it was against his will that Joseph took from him the birthright, as it is written (I Chr. 5, 1.) But when he defiled his father's bed was his birth-right given unto the sons of Joseph; yet he never envied him, for it is written (Gen. 37, 21.) And when Reuben heard it he delivered him out of their hands.'" Why was she named Ruth? R. Jochanan said "Be cause she merited that from her shall come forth David, who satisfied the Holy One, praised be He! with songs and praises." And whence do we derive that the name is the cause? R. Elazar said: "It is said (Ps. 46, 9.) Come, look at the deeds of the Lord, who hath made desolation on the earth. Do not read it Shamoth (desolation), but read Shemoth (names)."

Conversely, Leah spoke words of praise, and her offspring continued the tradition of praise. She declared: This time will I praise the Lord (Gen. 29:35); and of her son Judah it is said: Judah, thee thy brethren praise (ibid. 49:8). David (another descendant) said: Praise the Lord, for He is good (Ps. 118:1); and concerning Daniel it is said: Daniel kneeled upon his knees three times a day, and prayed, and praised (Dan. 6:11). R. Judah said: Silence is so very important that Rachel was privileged, because of her silence, to rear two additional tribes in Israel, Ephraim and Manasseh.

And God remembered Rachel. Prior to this verse, it is written: And Leah conceived again, and bore a son; and she said: “This time will I praise the Lord” (Gen. 29:35). Why did she not say I will praise the Lord after the births of Reuben, Simeon, Levi, and all the others, but only after the birth of Judah? This may be compared to a priest who goes to a man’s barn to collect the tithe⁸A tenth of a man’s possessions appropriated as a tax or sacrifice. The Mosaic law (Num. 18:21–26) made the tithe obligatory. and the priestly portion. When the owner of the barn hands the priest the priestly portion, he does not thank him, and when he gives him the tithe, he still does not thank him. But if, after he gives the priest what is due him, he adds a measure of unconsecrated food, the priest does thank him and recites a prayer in his behalf. A bystander asked the priest: “Why is it that when he gave you the tithe and the priestly portion, you did not thank him, but when he added only a single measure of unconsecrated food, you thanked him?” The priest replied: “The tithe and the priestly offering belong to me, and I merely accepted that which belonged to me, but the measure of unconsecrated food he added belonged to him, and so I thanked him for it.” Similarly Leah said: “Twelve tribes are to descend from Jacob, and since he has four wives, each of us is entitled to bear three sons. I have already given birth to three sons, my rightful share, but now a fourth son has been granted to me; surely it is fitting that I praise the Lord this time.” Therefore Rachel envied her sister (Gen. 30:1). The Holy One, blessed be He, declared: How long shall this righteous woman grieve? Is it not just that she too shall conceive? Should she not be at least equal to the handmaidens? Forthwith, And God remembered Rachel.

(Gen. 49:6:) FOR IN THEIR ANGER THEY KILLED A MAN, when they killed Shechem ben Hamor. He said to them: You have afflicted me. Immediately (in vs. 7): CURSED BE THEIR ANGER SO FIERCE. These tribes were unable to dwell together. Rather (ibid., cont.): I WILL DIVIDE THEM IN JACOB AND SCATTER THEM IN ISRAEL. Judah came in and < Jacob > praised him (in vs. 8): YOU, O JUDAH, YOUR BROTHERS SHALL PRAISE (rt.: YDH). In your case, your mother gave praise (rt.: YDH) through your name (Judah, rt.: YDH). When she bore you, she said (in Gen. 29:35): THIS TIME I WILL PRAISE (rt.: YDH) THE LORD; < THEREFORE SHE CALLED HIS NAME JUDAH (rt.: YDH) >. And what did she see to praise in Judah? It is simply that she had given birth to Reuben and foreseen Dathan and Abiram (in Numb. 16:1); so she had not given praise over him (i.e., Reuben). She had given birth to Simeon and foreseen Zimri; so she had not given praise over him. She had given birth to Levi and foreseen Korah; so she had not given praise over him. When she gave birth to Judah, she immediately gave praise (rt.: YDH) over him because he made a confession (rt.: YDH) in the Tamar incident, as stated (in Gen. 38:26): THEN JUDAH GAVE ACKNOWLEDGMENT AND SAID: SHE IS MORE RIGHTEOUS THAN I.⁶¹See Gen. R. 99 (another version):8 (= p. 1279 in the Theodor-Albeck edition). His father said to him: Your mother has given praise (rt.: YDH) over you, and you have made a confession (rt.: YDH). Therefore your brothers shall praise (rt.: YDH) you.⁶²Although the Buber text has “him” here, the correct reading must be “you.” When Isaac blessed Jacob, he had said to him (in Gen. 27:29): AND MAY YOUR MOTHER'S CHILDREN BOW DOWN TO YOU, since he had only one wife. But, since Jacob had four wives, he said (in Gen. 49:8): YOUR FATHER'S CHILDREN < SHALL BOW DOWN TO YOU >.⁶³Gen. R. 66:4. Why shall your brothers praise you? Because all Israel shall be called by your name, < i.e., > Jews.⁶⁴Gen. R. 98(99):6. In Hebrew the word “Jews” is simply the plural of Judah, which in turn has the same root as the Hebrew verb meaning “praise.” And not only that, but out of you is coming the Messiah, who is saving Israel, as stated (in Is. 11:10): BUT A SHOOT SHALL COME FORTH FROM THE STEM OF JESSE….⁶⁵Cf. Romans 15:12; Rev. 5:5.
