If Cain's revenge is sevenfold, then Lamech's is seventy-sevenfold."
Jesus said to him, "I do not say to you seven times, but seventy times seven.[7]
Then the LORD said to him, "Not so! If anyone kills Cain, vengeance shall be taken on him sevenfold." And the LORD put a mark on Cain, lest any who found him should attack him.
