Moffatt(i)
17 Never pay back evil for evil to anyone; aim to be above reproach in the eyes of all;
18 be at peace with all men, if possible, so far as that depends on you.
19 Never revenge yourselves, beloved, but let the Wrath of God have its way; for it is written, Vengeance is mine, I will exact a requital — the Lord has said it. No,
20 if your enemy is hungry, feed him, if he is thirsty, give him drink; for in this way you will make him feel a burning sense of shame.
21 Do not let evil get the better of you; get the better of evil by doing good.
