Genesis 4:16-20

And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden.

And Cain knew his wife; and she conceived, and bare Enoch: and he builded a city, and called the name of the city, after the name of his son, Enoch.

And unto Enoch was born Irad: and Irad begat Mehujael: and Mehujael begat Methusael: and Methusael begat Lamech.

And Lamech took unto him two wives: the name of the one was Adah, and the name of the other Zillah.

And Adah bare Jabal: he was the father of such as dwell in tents, and of such as have cattle.
