Genesis 4:23-25

Lamech said to his wives, “Adah and Zillah, listen to me; wives of Lamech, hear my words. I have killed a man for wounding me, a young man for injuring me. If Cain is avenged seven times, then Lamech seventy-seven times.” Adam made love to his wife again, and she gave birth to a son and named him Seth, saying, “God has granted me another child in place of Abel, since Cain killed him.”
