RKJNT(i)
18 If it is possible, as much as it lies with you, live peaceably with all men.
19 Dearly beloved, do not avenge yourselves, but rather give place for the wrath of God: for it is written, Vengeance is mine; I will repay, says the Lord.
20 Therefore, if your enemy is hungry, feed him; if he is thirsty, give him something to drink: for in so doing you shall heap coals of fire upon his head.
21 Do not be overcome by evil, but overcome evil with good.
