Genesis 4:17-26 - The Line Of Cain
17 And Cain knew his wife, and she conceived and bore Enoch. And he built a city; and he called the name of the city after the name of his son Enoch. 18 And to Enoch was born Irad; and Irad begot Mehujael; and Mehujael begot Methushael; and Methushael begot Lemech. 19 And Lemech took two wives: the name of the one was Adah, and the name of the second, Zillah. 20 And Adah bore Jabal: he was the father of those who dwell in tents, and breed cattle. 21 And his brother's name was Jubal: he was the father of those who handle the harp and pipe. 22 And Zillah, she also bore Tubal-Cain, the forger of every kind of tool of brass and iron. And the sister of Tubal-Cain was Naamah.
23 And Lemech said to his wives: Adah and Zillah, hear my voice, Ye wives of Lemech, listen to my speech. For I have slain a man for my wound, and a youth for my bruise. 24 If Cain shall be avenged seven-fold; Lemech seventy and seven fold.
25 And Adam knew his wife again, and she bore a son, and called his name Seth: ... For God has appointed me another seed instead of Abel, because Cain has slain him. 26 And to Seth, to him also was born a son; and he called his name Enosh. Then people began to call on the name of Jehovah.
