VENGEANCE IS THE LORD'S.

Don't make attempts to fight and defend yourself and others. It could cause a lot of trouble for you. Moses did and almost got killed for it. Vengeance rest in the Lord alone and not you. Hand over every wrong doer to God and don't attempt to recompense. God is the righteous judge and will do what's right for you. If you let God have His way, He will miraculously settle you, as He did for Joseph.
