Genesis 4:22-24

Authorized (King James) Version

²² And Zillah, she also bare Tubal-cain, an instructer of every artificer in brass and iron: and the sister of Tubal-cain 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.
