Genesis 4:17 WEB

¹⁵  Yahweh said to him, 'Therefore whoever slays Cain, vengeance will be taken on him sevenfold.' Yahweh appointed a sign for Cain, lest any finding him should strike him.

¹⁶  Cain went out from Yahweh's presence, and dwelt in the land of Nod, on the east of Eden.

¹⁷  Cain knew his wife. She conceived, and gave birth to Enoch. He built a city, and called the name of the city, after the name of his son, Enoch.

¹⁸  To Enoch was born Irad. Irad became the father of Mehujael. Mehujael became the father of Methushael. Methushael became the father of Lamech.

¹⁹  Lamech took two wives: the name of the one was Adah, and the name of the other Zillah.
