Genesis 4:23-25

Darby Translation

²³ And Lemech said to his wives: Adah and Zillah, hear my voice, Ye wives of Lemech, listen to my speech. For I have slain a man for my wound, and a youth for my bruise.

²⁴ If Cain shall be avenged seven-fold; Lemech seventy and seven fold.

²⁵ And Adam knew his wife again, and she bore a son, and called his name Seth: … For God has appointed me another seed instead of Abel, because Cain has slain him.
