15. And the Lord said to him: "By no means will it be so; rather, whoever would kill Cain, will be punished sevenfold." And the Lord placed a seal upon Cain, so that anyone who found him would not put him to death.
16. And so Cain, departing from the face of the Lord, lived as a fugitive on the earth, toward the eastern region of Eden.
17. Then Cain knew his wife, and she conceived and gave birth to Enoch. And he built a city, and he called its name by the name of his son, Enoch.
18. Thereafter, Enoch conceived Irad, and Irad conceived Mahujael, and Mahujael conceived Mathusael, and Mathusael conceived Lamech.
19. Lamech took two wives: the name of one was Adah, and the name of the other was Zillah.
20. And Adah conceived Jabel, who was the father of those who live in tents and are shepherds.
21. And the name of his brother was Jubal; he was the father of those who sing to the harp and the organ.
22. Zillah also conceived Tubalcain, who was a hammerer and artisan in every work of brass and iron. In fact, the sister of Tubalcain was Noema.
23. And Lamech said to his wives Adah and Zillah: "Listen to my voice, you wives of Lamech, pay attention to my speech. For I have killed a man to my own harm, and an adolescent to my own bruising.
24. Sevenfold vengeance will be given for Cain, but for Lamech, seventy-seven times."
25. Adam also knew his wife again, and she gave birth to a son, and she called his name Seth, saying, "God has given me another offspring, in place of Abel, whom Cain killed."
