[17] Cain made love to his wife, and she became pregnant and gave birth to Enoch. Cain was then building a city, and he named it after his son Enoch. [18] To Enoch was born Irad, and Irad was the father of Mehujael, and Mehujael was the father of Methushael, and Methushael was the father of Lamech. [19] Lamech married two women, one named Adah and the other Zillah. [20] Adah gave birth to Jabal; he was the father of those who live in tents and raise livestock. [21] His brother’s name was Jubal; he was the father of all who play stringed instruments and pipes. [22] Zillah also had a son, Tubal-Cain, who forged all kinds of tools out of bronze and iron. Tubal-Cain’s sister was Naamah. [23] Lamech said to his wives, “Adah and Zillah, listen to me; wives of Lamech, hear my words. I have killed a man for wounding me, a young man for injuring me. [24] If Cain is avenged seven times, then Lamech seventy-seven times.”
