Genesis 4:16-24 - Cain's Family
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 bore Enoch: and he built a city, and called the name of the city, after the name of his son Enoch. 18 And to Enoch was born Irad: and Irad begat Mehujael: and Mehujael begat Methusael: and Methusael begat Lamech. 19 And Lamech took to 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 organ. 22 And Zillah, she also bore Tubalcain, an instructor of every artificer in brass and iron: and the sister of Tubalcain was Naamah.
23 And Lamech said to his wives, Adah and Zillah, Hear my voice, ye wives of Lamech, hearken to my speech: for I have slain a man to my wounding, and a young man to my hurt. 24 If Cain shall be avenged seven-fold, truly Lamech seventy and seven-fold.
