Genesis 6:2-4

New Living Translation

² The sons of God saw the beautiful women^[a] and took any they wanted as their wives. ³ Then the Lord said, “My Spirit will not put up with^[b] humans for such a long time, for they are only mortal flesh. In the future, their normal lifespan will be no more than 120 years.”

⁴ In those days, and for some time after, giant Nephilites lived on the earth, for whenever the sons of God had intercourse with women, they gave birth to children who became the heroes and famous warriors of ancient times.
