Genesis 4:17-26
English Standard Version
Chapter 4
17Cain knew his wife, and she conceived and bore Enoch. When he built a city, he called the name of the city after the name of his son, Enoch. 18To Enoch was born Irad, and Irad fathered Mehujael, and Mehujael fathered Methushael, and Methushael fathered Lamech. 19And Lamech took two wives. The name of the one was Adah, and the name of the other Zillah. 20Adah bore Jabal; he was the father of those who dwell in tents and have livestock. 21His brother 's name was Jubal; he was the father of all those who play the lyre and pipe. 22Zillah also bore Tubal-cain; he was the forger of all instruments of bronze and iron. The sister of Tubal-cain was Naamah.
24 If Cain 's revenge is sevenfold, then Lamech 's is seventy-sevenfold."
25And Adam knew his wife again, and she bore a son and called his name Seth, for she said, "God has appointed for me another offspring instead of Abel, for Cain killed him."
26To Seth also a son was born, and he called his name Enosh. At that time people began to call upon the name of the Lord.
