Genesis 4:22-24 21st Century King James Version (KJ21)
22 And Zillah, she also bore Tubalcain, an instructor of every artificer in brass and iron; and the sister of Tubalcain was Naamah.
23 And Lamech said unto his wives, “Adah and Zillah, hear my voice; ye wives of Lamech, hearken unto my speech! For I have slain a man for my wounding, and a young man for my hurt.
24 If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold.”
