The earth also was corrupt before God
That is, the inhabitants of the earth were corrupt in their lives and conversations; they were corrupt both in principle and practice, and did abominable things; and those corruptions were, according to Jarchi, uncleanness and idolatry; they were corrupt in the worship of God, worshipping the creature more, or besides the Creator; and they were corrupt in their manners and behaviour to one another, being guilty of fornication and adultery, and other enormous crimes; of some against God, and of others against their neighbours; and these they committed openly and impudently, without any fear of God, or dread of his wrath and displeasure, and in contempt of him, his will and laws:
and the earth was filled with violence;
with doing injury to the persons and properties of men; with oppression and cruelty, by tyrannical decrees and unrighteous judgments; or with rapines and robberies, as the Targums and Jarchi; and with rapes, as Aben Ezra adds: the account that Lucian F24 gives from tradition agrees with this; that the present race of men is not the first, they totally perished by a flood; and those men were very insolent and addicted to unjust actions; for they neither kept their oaths, nor were hospitable to strangers, nor gave ear to suppliants, for which reason they were destroyed.
