Genesis 4:15-18 New International Reader's Version (NIRV)

15. But the Lord said to him, "No. Anyone who kills you will be paid back seven times." The Lord put a mark on Cain. Then anyone who found him wouldn't kill him.

16. So Cain went away from the Lord. He lived in the land of Nod. It was east of Eden.

17. Cain made love to his wife. She became pregnant and gave birth to Enoch. At that time Cain was building a city. He named it after his son Enoch.

18. Enoch had a son named Irad. Irad was the father of Mehujael. Mehujael was the father of Methushael. And Methushael was the father of Lamech.
