Midrash su Genesi 6:4

(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. Berechiah said: The men of the generation of the flood were exceedingly strong and tall, as it is written: These same were the mighty men (Gen. 6:4), and if He had not punished them with fire that descended from above, nothing would have been able to destroy them. Hence Job said: Surely their substance is cut off, and their abundance the fire hath consumed (Job 22:20).

All the great luminaries of the stars are situated in the south except Ursa Major, which is placed in the north. All the Mazziḳin which move in the firmament and the angels who fell from their holy place (even) from heaven, (when) they ascend to hear the (Divine) Word behind the veil they are pursued with a rod of fire, and they return to their place.
