Genesis 4:17-26 RSV

17 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 To Enoch was born Irad; and Irad was the father of Me-hu'ja-el, and Me-hu'ja-el the father of Me-thu'sha-el, and Me-thu'sha-el the father of Lamech.
19 And Lamech took two wives; the name of the one was Adah, and the name of the other Zillah.
20 Adah bore Jabal; he was the father of those who dwell in tents and have cattle.
21 His brother's name was Jubal; he was the father of all those who play the lyre and pipe.
22 Zillah bore Tubal-cain; he was the forger of all instruments of bronze and iron. The sister of Tubal-cain was Na'amah.
23 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.
24 If Cain is avenged sevenfold, truly Lamech seventy-sevenfold."
25 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."
26 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.
