'Vengeance' in the Bible

because these are days of vengeance, to fulfill all that is written.

Do not avenge yourselves, dear friends, but give place to God's wrath, for it is written, "Vengeance is mine, I will repay," says the Lord.

For we know the one who said, "Vengeance is mine, I will repay," and again, "The Lord will judge his people."
