When men began to increase in number on the earth and daughters were born to them,
² the sons of God saw that the daughters of men were beautiful, and they married any of them they chose. ³ Then the LORD said, "My Spirit will not contend with man forever, for he is mortal; his days will be a hundred and twenty years." ⁴ The Nephilim were on the earth in those days--and also afterward--when the sons of God went to the daughters of men and had children by them. They were the heroes of old, men of renown.

⁵ The LORD saw how great man's wickedness on the earth had become, and that every inclination of the thoughts of his heart was only evil all the time. ⁶ The LORD was grieved that he had made man on the earth, and his heart was filled with pain. ⁷ So the LORD said, "I will wipe mankind, whom I have created, from the face of the earth--men and animals, and creatures that move along the ground, and birds of the air--for I am grieved that I have made them." ⁸ But Noah found favor in the eyes of the LORD.
