Genesis 4:21

18 And unto Enoch was born Irad: and Irad begat Mehujael: and Mehujael begat Methusael: and Methusael 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 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 organ.

22 And Zillah, she also bare Tubalcain, an instructer of every artificer in brass and iron: and the sister of Tubalcain was Naamah.

23 And Lamech said unto his wives, Adah and Zillah, Hear my voice; ye wives of Lamech, hearken unto my speech: for I have slain a man to my wounding, and a young man to my hurt.

24 If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold.
