Genesis 4:18-24

18To Enoch was born Irad, and Irad fathered Mehujael, and Mehujael fathered Methushael, and Methushael fathered Lamech.

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."
