Genesis 6:4-6

Revised Geneva Translation

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.

⁵ When the LORD saw that the wickedness of man was great on the Earth (and all the imaginations of the thoughts of his heart were only evil continually),

⁶ then it caused the LORD to regret that He had made man on the Earth; and He was sorry in His heart.
