15 Yahweh said to him, “Therefore whoever slays Cain, vengeance will be taken on him sevenfold.” Yahweh appointed a sign for Cain, so that anyone finding him would not strike him.
16 Cain left Yahweh’s presence, and lived in the land of Nod, 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 first one was Adah, and the name of the second one was Zillah.
20 Adah gave birth to Jabal, who was the father of those who dwell in tents and have livestock.
21 His brother’s name was Jubal, who was the father of all who handle the harp and pipe.
