Proverbs 25:22

For thou shall heap coals of fire upon his head ,.... Not to increase his punishment and damnation, the more aggravated by kindness shown him; but to bring him by such means to a sense of former injuries, and to shame for them, repentance of them, and love of the person injured, and carefulness for the future of doing him any further wrong;

and the Lord shall reward thee : with good things, for all the good done to thine enemy, whether it has the desired effect on him or not; or whether he rewards thee or not; see Romans 12:20 .
