(9) This is the line of Noah.—Noah was a righteous man; he was blameless in his age; Noah walked with God.— (10) Noah begot three sons: Shem, Ham, and Japheth. (11) The earth became corrupt before God; the earth was filled with lawlessness. (12) When God saw how corrupt the earth was, for all flesh had corrupted its ways on earth, (13) God said to Noah, “I have decided to put an end to all flesh, for the earth is filled with lawlessness because of them: I am about to destroy them with the earth.
ותשחת. לְשׁוֹן עֶרְוָה וַעֲ"זָ (סנה' נ"ז) כְּמוֹ פֶּן תַּשְׁחִתוּן (דב' ד'), כִּי הִשְׁחִית כָּל בָּשָׂר וְגוֹ':
ותשחת [THE EARTH] WAS CORRUPT — It means lewdness and idolatry, as (Deuteronomy 4:16) פן תשחיתון “lest ye deal corruptly” (the following words show that this refers to idolatry) and as ‘כי השחית כל בשר וגו “for all flesh had corrupted etc.” (in next verse of this chapter where Rashi states that this has reference to lewdness) (Sanhedrin 57a).
ותמלא הארץ חמס. גֶּזֶל:
ותמלא הארץ חמס AND THE EARTH WAS FILLED WITH LAWLESSNESS — means robbery.
צדיק, שהיו מעשיו בצדק הפך אנשי דורו שהיו אנשי חמס.
צדיק, his deeds reflected justice, in contrast to those of his contemporaries, who were lawless men.
