Then Cain went away from the presence of the LORD, and dwelt in the land of Nod, east of Eden. 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. To Enoch was born Irad; and Irad was the father of Mehujael, and Mehujael the father of Methushael, and Methushael the father of Lamech. And Lamech took two wives; the name of the one was Adah, and the name of the other Zillah. Adah bore Jabal; he was the father of those who dwell in tents and have cattle. His brother's name was Jubal; he was the father of all those who play the lyre and pipe. Zillah bore Tubalcain; he was the forger of all instruments of bronze and iron. The sister of Tubalcain was Naamah. Lamech said to his wives: "Adah and Zillah, hear my voice; you wives of Lamech, hearken to what I say: I have slain a man for wounding me, a young man for striking me. If Cain is avenged sevenfold, truly Lamech seventy-sevenfold."
And Adam knew his wife again, and she bore a son and called his name Seth, for she said, "God has appointed for me another child instead of Abel, for Cain slew him." To Seth also a son was born, and he called his name Enosh. At that time men began to call upon the name of the LORD.
