Darby(i)
19 not avenging yourselves, beloved, but give place to wrath; for it is written, Vengeance [belongs] to me, *I* will recompense, saith the Lord.
20 If therefore thine enemy should hunger, feed him; if he should thirst, give him drink; for, so doing, thou shalt heap coals of fire upon his head.
21 Be not overcome by evil, but overcome evil with good.
