Genesis 6:4-6

Modern English Version

⁴ The Nephilim were on the earth in those days, and also after that, when the sons of God came in to the daughters of men, and they bore children to them. These were the mighty men who were of old, men of renown.

⁵ The Lord saw that the wickedness of man was great on the earth, and that every intent of the thoughts of his heart was continually only evil. ⁶ The Lord was sorry that He had made man on the earth, and it grieved Him in His heart.
