Genesis 6:2-4

Revised Geneva Translation

² Then the sons of God saw the daughters of men (that they were fair) and they took wives of all whom they liked.

³ Therefore the LORD said, “My spirit shall not always strive with man, because he is but flesh. And his days shall be a hundred and twenty years.”

⁴ There were giants on the Earth in those days—and also after that—when the sons of God came into the daughters of men, and children had been borne to them. These were mighty men, who, in old time, were men of renown.
