Genesis 4:13-18

Cain replied to the LORD, “My punishment is too great for me to bear! You have banished me from the land and from your presence; you have made me a homeless wanderer. Anyone who finds me will kill me!” The LORD replied, “No, for I will give a sevenfold punishment to anyone who kills you.” Then the LORD put a mark on Cain to warn anyone who might try to kill him. So Cain left the LORD’s presence and settled in the land of Nod, east of Eden. Cain had sexual relations with his wife, and she became pregnant and gave birth to Enoch. Then Cain founded a city, which he named Enoch, after his son. Enoch had a son named Irad. Irad became the father of Mehujael. Mehujael became the father of Methushael. Methushael became the father of Lamech.
