15 Then the Lord said to him, "Not so! If anyone kills Cain, vengeance shall be taken on him sevenfold." And the Lord put a mark on Cain, lest any who found him should attack him.

16 Then Cain went away from the presence of the Lord and settled in the land of Nod, east of Eden.

17 Cain knew his wife, and she conceived and bore Enoch. When he built a city, he called the name of the city after the name of his son, Enoch.
