Genesis 6:5

The wickedness of man—great, &c.— God saw their wickedness to be great, after the period of the hundred and twenty years which he had granted them to return and repent; he saw that they amended not, but arrived at the highest pitch of depravity, both in principle and practice. The longevity of the antediluvians is alone sufficient to account for that enormous height of wickedness to which they arose, according to this text and the traditions we have of their excessive lust, impiety, and violence.
