GENESIS 4:19-24 (KJV)

¹⁹And Lamekh took unto him two wives: the name of the one was Adah, and the name of the other Zillah. ²⁰And Adah bare Yabal: he was the father of such as dwell in tents, and of such as have cattle. ²¹And his brother’s name was Yubal: he was the father of all such as handle the harp and organ. ²²And Zillah, she also bare Tubal Qayin, an instructer of every artificer in brass and iron: and the sister of Tubal Qayin was Naamah. ²³And Lamekh said unto his wives, Adah and Zillah, Hear my voice; ye wives of Lamekh, hearken unto my speech: for I have slain a man to my wounding, and a young man to my hurt. ²⁴If Qayin shall be avenged sevenfold, truly Lamekh seventy and sevenfold.
