Proverbs 20:22

Say not thou, I will recompense evil,.... With evil; do an injury to one that has done one to you; private revenge is not to be taken, but should be left to God, to whom vengeance belongs,

Deuteronomy 32:35;

[but] wait on the Lord, and he shall save thee; commit thyself and cause to God; leave it with him to avenge thy wrongs; wait upon him in the way of thy duty, and wait his own time to do thee justice; he will at the proper season, and in his own way, save thee from thine enemy, and make a righteous retribution to him.
