Genesis 4:19-24

19And Lamech took two wives. The name of the one was Adah, and the name of the other Zillah.

20Adah bore Jabal; he was the father of those who dwell in tents and have livestock.

21His brother's name was Jubal; he was the father of all those who play the lyre and pipe.

22Zillah also bore Tubal-cain; he was the forger of all instruments of bronze and iron. The sister of Tubal-cain was Naamah.

23Lamech said to his wives: "Adah and Zillah, hear my voice; you wives of Lamech, listen to what I say: I have killed a man for wounding me, a young man for striking me.

24If Cain's revenge is sevenfold, then Lamech's is seventy-sevenfold."
