Prayers of vengeance are prayers that commit vengeance to the Lord. This is the way of faith: to recognize that God is the judge and to leave the execution of justice in his hands according to his time.1 Whereas Saul sought to avenge himself on those who did him wrong (1 Samuel 14:24; 1 Samuel 18:25), David left vengeance in the hands of the Lord.2
12 May the LORD judge between me and you, may the LORD avenge me against you, but my hand shall not be against you.
