Genesis 6:1-3

21st Century King James Version

6 And it came to pass, when men began to multiply on the face of the earth and daughters were born unto them,

² that the sons of God saw the daughters of men, that they were fair; and they took for themselves wives of all whom they chose.

³ And the Lord said, “My Spirit shall not always strive with man, for he also is flesh; yet his days shall be a hundred and twenty years.”
