Romans 12:19-21
(19) Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord.
(20) Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head.
(21) Be not overcome of evil, but overcome evil with good.
Referring again to the negative (cf. v. 17a) Paul then exhorted his readers not to take revenge after they are misused. Instead they should leave room for God’s wrath (lit., “for the wrath”), because God has promised to avenge His people: It is Mine to avenge, I will repay (Deut. 32:35; cf. Heb. 10:30). David’s refusal to kill Saul on two occasions when it seemed that God had delivered Saul into David’s hands is a classic biblical example of this principle. In light of God’s promise to execute vengeance, a Christian should therefore feed his enemy and quench his thirst—in short, respond to his evil with Christian love. Heaping burning coals on his head, along with the first part of Romans 12:20, is a quotation from Proverbs 25:21-22. The coals on the head may refer to a ritual in Egypt in which a person showed his repentance by carrying a pan of burning charcoal on his head. Helping rather than cursing an enemy may cause him to be ashamed and penitent. As Paul summarized, Do not be overcome by evil, giving in to the temptation to retaliate, but overcome evil with good (cf. Matt. 5:44, “love your enemies”). Again positive and negative commands are put together (cf. Rom. 12:9, 11, 16-20).
