Genesis 4:17-20

And Cain knew his wife, and she conceived and bore Ē´noch. And he built a city, and called the name of the city after the name of his son—Ē´noch. To Ē´noch was born Irad; and Irad begot Mehujael, and Mehujael begot Methushael, and Methushael begot Lamech. Then Lamech took for himself two wives: the name of one was Adah, and the name of the second was Zillah. And Adah bore Jabal. He was the father of those who dwell in tents and have livestock.
