It happened, when men began to multiply on the surface of the ground, and daughters were born to them,
that God's sons saw that men's daughters were beautiful, and they took for themselves wives of all that they chose.
The LORD said, "My spirit will not strive with man forever, because he also is flesh; yet will his days be one hundred twenty years."
The Nefilim were in the eretz in those days, and also after that, when God's sons came to men's daughters. They bore children to them: the same were the mighty men who were of old, men of renown.
The LORD saw that the wickedness of man was great in the eretz, and that every imagination of the thoughts of his heart was only evil continually.
The LORD was sorry that he had made man on the eretz, and it grieved him in his heart.
