3 So the Lord said, “My Spirit will not remain in humankind indefinitely, since they are mortal. They will remain for 120 more years.” 4 The Nephilim were on the earth in those days (and also after this) when the sons of God would sleep with the daughters of humankind, who gave birth to their children. They were the mighty heroes of old, the famous men. 5 But 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.

1 And all the others them took wives for themselves, each choosing one for himself, and they began to unite with them and defiled themselves with them. They taught them sorcery, spells, and the art of extracting medicinal substances from plants. 2 The women became pregnant and gave birth to enormous giants, whose height was three thousand ells. 3 These giants consumed everything humans produced. And when humans could no longer support them, 4 the giants turned against them and devoured mankind.

24 O Israel, how great is the house of God, how vast the territory that he possesses! 25 It is great and has no bounds; it is high and immeasurable. 26 The giants were born there, who were famous of old, great in stature, expert in war. 27 God did not choose them, or give them the way to knowledge; 28 so they perished because they had no wisdom, they perished through their folly.
