Midrash su Genesi 25:12

(Gen. 25:19:) THESE ARE THE GENERATIONS OF ISAAC BEN ABRAHAM.¹Except for most of the last section (# 24), Toledot is not found in Buber’s Oxford MS. Buber has filled in the gap mostly from Codex Vaticanus Ebr. 34. This text is related (to Prov. 17:6): GRANDCHILDREN ARE A CROWN FOR ELDERS, AND THE GLORY OF CHILDREN IS THEIR PARENTS.²Cf. Gen. R. 63:2; Tanh., Gen. 6:4. Who caused Abraham to be magnified? Jacob, as stated (in Is. 29:22): THUS SAYS THE LORD UNTO THE HOUSE OF JACOB, WHICH REDEEMED ABRAHAM. Why? Because, if one is meritorious as a Torah scholar together with his son and his grandson, it will never again be cut off from him. Thus it is stated (in Deut. 4:9f.): AND MAKE THEM (the statutes and ordinances) KNOWN TO YOUR CHILDREN AND GRANDCHILDREN AS ON THE DAY THAT YOU STOOD < BEFORE THE LORD YOUR GOD AT HOREB >. Just as the gift of < the > Torah did not become cease on the day it was given; so for one who teaches his son and his grandson Torah, it shall never again depart from him. And so it was when the Holy One saw Abraham was busy with the Torah. Where is it shown? Where it is stated (in Gen. 26:5): BECAUSE ABRAHAM HEEDED MY VOICE < AND KEPT MY CHARGE: MY COMMANDMENTS, MY STATUTES, AND MY LAWS >. It is also written (above, in 18:19): FOR I HAVE KNOWN HIM. Then Jacob arose up and did not move from the Torah, as stated (in Gen. 25:27): BUT JACOB WAS A PERFECT MAN WHO SAT IN THE TENTS (i.e., in the academies).³For this interpretation, see Gen. R. 63:10; Targum Onqelos, Gen. 25:27; PRK 5:7. What stipulation did the Holy One make with them? (According to Josh. 1:8:) < THIS > BOOK OF THE LAW SHALL NOT DEPART < FROM YOUR MOUTH >…. It is also written (in Prov. 10:1): A WISE SON SHALL MAKE A FATHER GLAD. This is Isaac, since it is stated (in Gen. 21:12): FOR IN ISAAC SHALL YOUR SEED BE NAMED. (Prov. 10:1, cont.:) BUT A FOOLISH SON. This is Ishmael. Thus it is written (in Gen. 25:12): NOW THESE ARE THE GENERATIONS OF ISHMAEL BEN ABRAHAM. There are children who suffer disgrace through their parents. Josiah suffered disgrace through his father, as stated (in II Chron. 33:23): FOR AMON INCURRED A LOT OF GUILT. Hezekiah suffered disgrace through < his father > Ahaz, as stated (in Is. 8:16): BIND UP THE TESTIMONY.⁴According to Gen. R. 42:3; Lev. R. 11:7; Ruth R., proem 7; and Esther R., proem 11, this verse alludes to Ahaz, who had seized (ahaz) the synagogues and the academies. There are also parents who suffer disgrace through their children. Eli suffered disgrace through his sons, [as stated (in I Sam. 2:12): NOW ELI'S SONS WERE SCOUNDRELS. And Samuel also suffered disgrace through his sons], as stated (in I Sam. 8:3): BUT HIS SONS DID NOT WALK IN HIS WAYS. It did not, however, turn out in this way for Abraham. Instead he was magnified through Isaac, as stated (in Gen. 25:19, cont.): ABRAHAM SIRED ISAAC. Did he sire no one but Isaac? Now look, it is written {(in Gen. 25:19): THESE ARE THE GENERATIONS OF ISHMAEL.} [(in Gen. 16:15): SO HAGAR BORE A SON TO ABRAM.] And in addition < there are > the sons of Keturah: Zimran and Jokshan, < etc. > (cf. Gen. 25:2). But it does not say that Abraham sired anyone but Isaac, simply because Isaac was righteous. It is therefore stated (in Gen. 25:19): ABRAHAM SIRED ISAAC.

and Ishmael took his children and all the property that he had gained, together with the souls ‎of his household and all belonging to him, and they went to locate where they should find a ‎suitable place, And they went and dwelt near the wilderness of Paran and their dwelling was ‎from Havilah unto Shur, that is before Egypt as thou comest toward Assyria; and Ishmael and ‎his sons dwelt in the land, and they had chidren born unto them, and they were fruitful and ‎increased greatly. And these are the names of the sons of Nebayoth, the first born of Ishmael: ‎Mend, and Send, and Mayon; and the sons of Kedar were: Alyon, and Kezem, and Chamad, ‎and Eli. And the sons of Adbeel were: Cha mad, and Jabin; and the sons of Mibsam were: ‎Obadiah, and Ebedmelech, and Yeush—these are the families of the children of Ribah, the ‎wife of Ishmael; and the sons of Mishma, the son of Ishmael, were: Shamua, and Zecaryon, ‎and Obed; and the sons of Dumah were: Kezed, and Eli, and Machmad, and Amed; and the ‎sons of Masa were: Melon, and Mula, and Ebidadon; and the sons of Chadad were: Azur, and ‎Minzar, and Ebed melech; and the sons of Tema were: Seir, and Sadon, and Yakol; and the ‎sons of Yetur were: Merith, and Yaish, and Alyo, and Pachoth; and the sons of Naphish were: ‎Ebed, and Tamed, and Abiyasaph, and Mir; and the sons of Kedma were: Calip, and Tachti, and ‎Omir—these were the children of Malchuth, the wife of Ishmael, according to their families. ‎All these are the families of Ishmael according to their generations, and they dwelt in those ‎lands wherein they had built themselves cities unto this day.‎ And Rebekah, the daughter of Bethuel, the wife of Isaac, Abraham’s son, was barren in those ‎days, she had no offspring. And Isaac dwelt with his father in the land of Canaan, and the Lord ‎was with Isaac; and Arpachshad, son of Shem, the son of Noah, died at that time, in forty-‎eighth year of Isaac’s life; and all the days of Arpachshad’s life were four hundred and thirty ‎years when he died.‎

It happened again that the Egyptians summoned Israel before Alexander of Macedonia, saving to them: "The passage reads (Ex. 12, 36) And the Lord hath given the people favor in the eyes of the Egyptians, so that they gave unto them what they required; and they emptied out Egypt." And G'bihah b. P'sisa said to the sages: "Permit me, and I will appear before Alexander as advocate for the defendant Israel; if they defeat me, you will say to them, 'You have defeated an ignoramus among us,' and if I defeat them, you will say to them, 'The Torah of Moses defeated you'." They gave him permission, and he went to argue with them. He said to them: "Whence is your evidence? And they answered: "From your Torah." Then said he: "I, in defence, will also bring my evidence from the Torah. It is said (Ib. ib. 40) Now the time of the residence of the children of Israel, which they dwelt in Egypt, was four hundred and thirty years. Hence I demand of you the wages for the labor of six hundred thousand men whom your parents compelled to work for them during all the time they were in Egypt." King Alexander said to them: "State your argument against him." Whereupon they requested three days' time, which was granted them. But they could find nothing in reply, so they fled, leaving their sown fields and their planted vineyards. And that year also was a Sabbatical one. And it happened again that the descendants of Ishmael and the descendants of Keturah summoned Israel before Alexander, saying: "The land of Canaan belongs to us and to you, as it is said (Gen. 25, 12) These are the generations of Ishmael, Abraham's son, and it is written (Ib.) And these are the generations of Isaac, the son of Abraham." And again G'bihah b. P'sisa said to the sages: "Permit me, and I will appear before Alexander as advocate for the defendant Israel, and if they defeat me, say to them, 'You have defeated an ignoramus among us'; and if I defeat them, say to them, 'The law of Moses has defeated you." They granted him permission, and he went to argue with them. He said to them: "Whence is your evidence?" They said: "From your Torah." Then said he: "I, in defence, will also bring my evidence from the Torah. It is said (Ib. ib. 5) And Abraham gave all that he had unto Isaac. But unto the sons of the concubines that Abraham had, Abraham gave gifts; and he sent them away from Isaac his son." Now, if a father who made a legatum (bequest) to his children, and separated them while he was still alive, can the heirs have any claim against one another?"
