Genesis 6:3, 5-7

And Jehovah said, My Spirit shall not strive with man for ever, for that he also is flesh: yet shall his days be a hundred and twenty years.

And Jehovah saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. And it repented Jehovah that he had made man on the earth, and it grieved him at his heart. And Jehovah said, I will destroy man whom I have created from the face of the ground; both man, and beast, and creeping things, and birds of the heavens; for it repenteth me that I have made them.
