Genesis 4:24

24“If Cain is avenged sevenfold [as the Lord said he would be],

Then Lamech [will be avenged] 4:24 Lamech arrogantly declares to his wives that if someone kills him, he will be entitled to far greater vengeance since he merely retaliated for harm suffered, while Cain’s murder of Abel was by comparison unprovoked.seventy-sevenfold.”
