Genesis 6:1-4

The number of people on earth continued to increase. When these people had daughters, the sons of God saw how beautiful they were. So they chose the women they wanted. They married them, and the women had their children. Then the LORD said, “People are only human. I will not let my Spirit be troubled by them forever. I will let them live only 120 years.” During this time and also later, the Nephilim people lived in the land. They have been famous as powerful soldiers since ancient times.
