'Vengeance' in the Bible

because these are days of vengeance, so that all things which are written will be fulfilled.

And when he saw one of them being treated unjustly, he defended him and took vengeance for the oppressed by striking down the Egyptian.

Never take your own revenge, beloved, but leave room for the wrath of God, for it is written, “Vengeance is Mine, I will repay,” says the Lord.

For we know Him who said, “Vengeance is Mine, I will repay.” And again, “The Lord will judge His people.”
