Vengeance undone

“Adah amd Zillah, hear my voice,
Lamech’s wives, listen to what I say:
I killed a man for wounding me,
a boy for striking me.
Sevenfold vengeance is taken for Cain,
but seventy-sevenfold for Lamech.”

— Lamech speaking in Genesis 4:23-24

Then Peter went up to him and said, “Lord, how often must I forgive my brother if he wrongs me? As often as seven times? Jesus answered, “Not seven, I tell you, but seventy-seven times.”

— Matthew 18:21-22
