Genesis 6:1-9 American Standard Version (ASV)
6 And it came to pass, when men began to multiply on the face of the ground, and daughters were born unto them, 2 that the sons of God saw the daughters of men that they were fair; and they took them wives of all that they chose. 3 And Jehovah said, My Spirit shall not [a]strive with man for ever, [b]for that he also is flesh: [c]yet shall his days be a hundred and twenty years. 4 The [d]Nephilim were in the earth in those days, and also after that, when the sons of God came in unto the daughters of men, and they bare children to them: the same were the mighty men that were of old, the men of renown.
5 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. 6 And it repented Jehovah that he had made man on the earth, and it grieved him at his heart. 7 And Jehovah said, I will [e]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. 8 But Noah found favor in the eyes of Jehovah.
9 These are the generations of Noah. Noah was a righteous man, and [f]perfect in his generations: Noah walked with God.
