Genesis 4:16-24 - Cain's Family
16 And Cain goeth out from before Jehovah, and dwelleth in the land, moving about east of Eden;
17 and Cain knoweth his wife, and she conceiveth, and beareth Enoch; and he is building a city, and he calleth the name of the city, according to the name of his son -- Enoch. 18 And born to Enoch is Irad; and Irad hath begotten Mehujael; and Mehujael hath begotten Methusael; and Methusael hath begotten Lamech. 19 And Lamech taketh to himself two wives, the name of the one Adah, and the name of the second Zillah. 20 And Adah beareth Jabal, he hath been father of those inhabiting tents and purchased possessions; 21 and the name of his brother is Jubal, he hath been father of every one handling harp and organ. 22 And Zillah she also bare Tubal-Cain, an instructor of every artificer in brass and iron; and a sister of Tubal-Cain is Naamah.
23 And Lamech saith to his wives: -- 'Adah and Zillah, hear my voice; Wives of Lamech, give ear to my saying: For a man I have slain for my wound, Even a young man for my hurt; 24 For sevenfold is required for Cain, And for Lamech seventy and sevenfold.'
