Genesis 4:17-20

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. Lamech married two women. The first was named Adah, and the second was Zillah. Adah gave birth to Jabal, who was the first of those who raise livestock and live in tents.
