15. And the LORD said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the LORD appointed a sign for Cain, lest any finding him should smite 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.
18. And unto Enoch was born Irad: and Irad begat Mehujael: and Mehujael begat Methushael: and Methushael begat Lamech.
19. And Lamech took unto him two wives: the name of the one was Adah, and the name of the other Zillah.
20. And Adah bare Jabal: he was the father of such as dwell in tents and have cattle.
21. And his brother's name was Jubal: he was the father of all such as handle the harp and pipe.
