Genesis 4:15-17

Authorized (King James) Version

¹⁵ And the Lord said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the Lord set a mark upon Cain, lest any finding him should kill him.

¹⁶ And Cain went out from the presence of the Lord, and dwelt in the land of Nod, on the east of Eden. ¹⁷ And Cain knew his wife; and she conceived, and bare Enoch: and he builded a city, and called the name of the city, after the name of his son, Enoch.
