Before · Genesis 4:22–23
22Zillah also gave birth to Tubal Cain, the forger of every cutting instrument of bronze and iron. Tubal Cain’s sister was Naamah. 23Lamech said to his wives, “Adah and Zillah, hear my voice. You wives of Lamech, listen to my speech, for I have slain a man for wounding me, a young man for bruising me.
24If Cain will be avenged seven times, truly Lamech seventy-seven times.”
