Genesis 4:16-24 - Cain's Family
16 And Cain went away from before the face of the Lord, and made his living-place in the land of Nod on the east of Eden.
17 And Cain had connection with his wife and she became with child and gave birth to Enoch: and he made a town, and gave the town the name of Enoch after his son. 18 And Enoch had a son Irad: and Irad became the father of Mehujael: and Mehujael became the father of Methushael: and Methushael became the father of Lamech. 19 And Lamech had two wives; the name of the one was Adah, and the name of the other Zillah. 20 And Adah gave birth to Jabal: he was the father of such as are living in tents and keep cattle. 21 And his brother's name was Jubal: he was the father of all players on instruments of music. 22 And Zillah gave birth to Tubal-cain, who is the father of every maker of cutting instruments of brass and iron: and the sister of Tubal-cain was Naamah.
23 And Lamech said to his wives, Adah and Zillah, give ear to my voice; you wives of Lamech, give attention to my words, for I would put a man to death for a wound, and a young man for a blow; 24 If seven lives are to be taken as punishment for Cain's death, seventy-seven will be taken for Lamech's.
