Genesis 6:1-7

1When humankind began to multiply on the face of the earth, and daughters were born to them,

2the sons of God saw that the daughters of humankind were beautiful. Thus they took wives for themselves from any they chose.

3So the Lord said, “My spirit will not remain in humankind indefinitely, since they are mortal. They will remain for 120 more years.”

4The Nephilim were on the earth in those days (and also after this) when the sons of God were having sexual relations with the daughters of humankind, who gave birth to their children. They were the mighty heroes of old, the famous men.

5But the Lord saw that the wickedness of humankind had become great on the earth. Every inclination of the thoughts of their minds was only evil all the time.

6The Lord regretted that he had made humankind on the earth, and he was highly offended.

7So the Lord said, “I will wipe humankind, whom I have created, from the face of the earth – everything from humankind to animals, including creatures that move on the ground and birds of the air, for I regret that I have made them.”
