17. And Cain knew his wife; and she conceived, and bore Enoch: and he built 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 bore Jabal: he was the father of such as dwell in tents, and of such as have cattle.
21. And his brother's name was Jubal: he was the father of all such as handle the harp and pipe.
