Genesis 4:22-24

King James Version

²² And Zillah, she also bare Tubalcain, an instructer 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 to my wounding, and a young man to my hurt.

²⁴ If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold.
