Genesis 6:2-3

Amplified Bible

² that the ^[a]sons of God saw that the daughters of men were beautiful and desirable; and they took wives for themselves, whomever they chose and desired. ³ Then the Lord said, “My Spirit shall not strive and remain with man forever, because he is indeed flesh [sinful, corrupt—given over to sensual appetites]; nevertheless his days shall yet be ^[b]a hundred and twenty years.”
