Midrash su Isaia 29:22

(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.

R. Samuel b. Nachmeni in the name of R. Jonathan said: "He who teaches the Torah to the son of his neighbor, Scripture considers him as if he begot him, as it is said (Num. 3, 1) And these are the generations of Aaron and Moses; and the following verse reads: And these are the names of the sons of Aaron, to teach you that Aaron begot [his sons] but Moses taught them, therefore they are recorded under his name." (Is. 29, 22) Therefore thus hath said the Lord unto the house of Jacob, he who hath redeemed Abraham. Where do we find that Jacob redeemed Abraham? R. Juda said: "He redeemed him from the trouble of rearing children. And this is what is meant by the passage (Ib) Not now shall Jacob be ashamed, and not now shall his face he made pale — i.e., he shall not be ashamed of his father and his face shall not become pale because of his grandfather."

These are the generations of Isaac, Abraham’s son: Abraham begot Isaac (Gen. 25:9). Scripture states elsewhere in allusion to this verse: Children’s children are the crown of old men; and the glory of children are their fathers (Prov. 17:6). The righteous are “regaled” (i.e. saved) by their grandchildren, and their children are regaled by their fathers. How do we know this? We know it because Abraham was saved for Jacob’s sake. After Nimrod caused Abraham to be hurled into the fiery furnace, the Holy One, blessed be He, descended to rescue him. The ministering angels thereupon exclaimed: Master of the Universe, why do You trouble to save him, since so many wicked men will descend from him? The Holy One, blessed be He, replied: I shall save him for the sake of his grandson Jacob, who will descend from him. Whence do we know this to be so? R. Berechiah said: It is written: Thus saith the Lord who redeemed Abraham, concerning the house of Jacob (Isa. 29:22); that is, He redeemed him from the furnace for the sake of Jacob. Hence, fathers are saved for the sake of their descendants.

As to Jacob, the Holy One, named him also, as it is said: And his name was called Jacob (ibid. 25:26). The four letters in Jacob’s name in Hebrew correspond to the four crowns through which his descendants adored the Holy One, blessed be He. The yod corresponds to the Ten Commandments, the ayin (seventy) corresponds to the seventy elders, the kuf (one hundred) to the Temple, which was one hundred cubits high, that his descendants erected for the Holy One, blessed be He, as it is said: And he measured the house, a hundred cubits (Ezek. 41:13), and the bet (two) corresponds to the two tablets on which were inscribed the Ten Commandants. They were redeemed from Egypt by Jacob’s merit, as it is said: And He established it unto Jacob for a statute (Ps. 105:10). Were it not for Jacob, Abraham would not have been redeemed from the furnace, as it is said: Therefore, thus saith the Lord, who redeemed Abraham, concerning the house of Jacob (Isa. 29:22). However, as for Esau, his father and mother named him, as it is said: And they called his name Esau (Gen. 25:25). About him, Scripture states: His remembrance shall perish from the earth, and he shall have no name abroad (Job 18:7).
