Genesis 4:17 WBT

¹⁵  And the LORD said to him, Therefore whoever slayeth Cain, vengeance shall be taken on him seven-fold. And the LORD set a mark upon Cain, lest any finding him should kill him.

¹⁶  And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden.

¹⁷  And Cain knew his wife, and she conceived, and bore Enoch: and he built a city, and called the name of the city, after the name of his son Enoch.

¹⁸  And to Enoch was born Irad: and Irad begat Mehujael: and Mehujael begat Methusael: and Methusael begat Lamech.

¹⁹  And Lamech took to him two wives: the name of the one [was] Adah, and the name of the other Zillah.
