(9) This is the line of Noah.—Noah was a righteous man; he was blameless in his age; Noah walked with God.—

בדורותיו IN HIS GENERATIONS — Some of our Rabbis explain it (this word) to his credit: he was righteous even in his generation; it follows that had he lived in a generation of righteous people he would have been even more righteous owing to the force of good example. Others, however, explain it to his discredit: in comparison with his own generation he was accounted righteous, but had he lived in the generation of Abraham he would have been accounted as of no importance (cf. Sanhedrin 108a).

את האלהים התהלך נח NOAH WALKED WITH GOD — In the case of Abraham Scripture says, (Genesis 24:40) ‘‘[God] before whom I walked”; Noah needed God’s support to uphold him in righteousness, Abraham drew his moral strength from himself and walked in his righteousness by his own effort (Genesis Rabbah 30:10).

Make yourself an ark of gopher wood; make it an ark with compartments, and cover it inside and out with pitch.

עשה לך תבת MAKE THEE AN ARK — There are numerous ways by which God could have saved Noah; why, then, did he burden him with this construction of the Ark? So that the men of the generation of the Flood might see him employed on it for 120 years and might ask him, “What do you need this for”? and so that he might answer them, “The Holy One, blessed be He, is about to bring a flood upon the world” — perhaps they might repent (Sanhedrin 108b).

“For My part, I am about to bring the Flood—waters upon the earth—to destroy all flesh under the sky in which there is breath of life; everything on earth shall perish.

מבול A FLOOD — so called because it ruined (בלה) everything; because it cast everything into confusion (בלל), and because it brought (הוביל from root יבל) everything down from the heights to a lower level. And this last explanation underlies the translation of Onkelos who translates it by טופנא (Ar. טוף = Heb. צוף) because the Flood caused everything to float about and brought it (the Ark) to Babel which is a low-lying district. That is the reason why it (Babylon) is called, also, Shinar (שנער): because all those who died through the Flood were shaken out (ננערו) into it (Shabbat 113b).
