Genesis 6:3-5

New Life Version

³ Then the Lord said, “My Spirit will not stay in man forever, for he is flesh. But yet he will live for 120 years.” ⁴ Very large men were on the earth in those days, and later also, when the sons of God lived with the daughters of men, who gave birth to their children. These were the powerful men of long ago, men of much strength.

⁵ Then the Lord saw that man was very sinful on the earth. Every plan and thought of the heart of man was sinful always.
