Genesis 4:16-24 - Cain's Family
16 And Cain went out from the face of the LORD, and dwelt in the land Nod, on the east side of Eden.
17 And Cain lay with his wife, which conceived and bare Enoch. And he was building a city and called the name of it after the name of his son, Enoch. 18 And Enoch begat Irad. And Irad begat Mehujael. And Mehujael begat Methusael. And Methusael begat Lamech. 19 And Lamech took him two wives: the one was called Adah, and the other Zillah. 20 And Ada bare Jabal; of whom came they that dwell in tents and possess cattle. 21 And his brother's name was Jubal; of him came all that exercise themselves on the harp and on the organs. 22 And Zillah she also bare Tubalcain; a worker in metal and a father of all that grave in brass and iron. And Tubalcain's sister was called Naamah.
23 Then said Lamech unto his wives Adah and Zillah, "Hear my voice ye wives of Lamech, and hearken unto my words, for I have slain a man and wounded myself, and have slain a young man, and got myself stripes. 24 For Cain shall be avenged sevenfold: but Lamech seventy times sevenfold."
