18 If it is possible, in so far as you are able, be at peace with all men.
19 Do not defend yourselves, dearest ones. Instead, step aside from wrath. For it is written: "Vengeance is mine. I shall give retribution, says the Lord."
20 So if an enemy is hungry, feed him; if he is thirsty, give him a drink. For in doing so, you will heap burning coals upon his head.
21 Do not allow evil to prevail, instead prevail over evil by means of goodness.
