Genesis 4:17-20

17Cain was intimate with his wife, and she conceived and gave birth to Enoch. Then Cain became the builder of a city, and he named the city Enoch after his son.

18Irad was born to Enoch, Irad fathered Mehujael, Mehujael fathered Methushael, and Methushael fathered Lamech.

19Lamech took two wives for himself, one named Adah and the other named Zillah.

20Adah bore Jabal; he was the first of the nomadic herdsmen.
