15. “No!” the Lord answered. “Anyone who kills you will be punished seven times worse than I am punishing you.” So the Lord put a mark on Cain to warn everyone not to kill him.
16. But Cain had to go far from the Lord and live in the Land of Wandering, which is east of Eden.
17. Later, Cain and his wife had a son named Enoch. At the time Cain was building a town, and so he named it Enoch after his son.
18. Then Enoch had a son named Irad, who had a son named Mehujael, who had a son named Methushael, who had a son named Lamech.
19. Lamech married Adah, then Zillah.
20-21. Lamech and Adah had two sons, Jabal and Jubal. Their son Jabal was the first to live in tents and raise sheep and goats. Jubal was the first to play harps and flutes.
