'Avenger' in the Bible

For government is God’s servant for your good. But if you do wrong, be afraid, because it does not carry the sword for no reason. For government is God’s servant, an avenger that brings wrath on the one who does wrong.

This means one must not transgress against and defraud his brother in this matter, because the Lord is an avenger of all these offenses, as we also previously told and warned you.
