15. And the Lord said to him, “Therefore, whoever kills Cain, vengeance shall be taken on him sevenfold.” And the Lord set a mark on Cain, lest anyone finding him should kill him.
16. Then 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 Ē´noch. And he built a city, and called the name of the city after the name of his son—Ē´noch.
18. To Ē´noch was born Irad; and Irad begot Mehujael, and Mehujael begot Methushael, and Methushael begot Lamech.
19. Then Lamech took for himself two wives: the name of one was Adah, and the name of the second was Zillah.
20. And Adah bore Jabal. He was the father of those who dwell in tents and have livestock.
21. His brother’s name was Jubal. He was the father of all those who play the harp and flute.
22. And as for Zillah, she also bore Tubal-Cain, an instructor of every craftsman in bronze and iron. And the sister of Tubal-Cain was Naamah.
23. Then Lamech said to his wives:“Adah and Zillah, hear my voice;Wives of Lamech, listen to my speech!For I have killed a man for wounding me,Even a young man for hurting me.
24. If Cain shall be avenged sevenfold,Then Lamech seventy-sevenfold.”
25. And Adam knew his wife again, and she bore a son and named him Seth, “For God has appointed another seed for me instead of Abel, whom Cain killed.”
