Do not repay anyone evil for evil; be concerned for what is noble in the sight of all. If possible, on your part, live at peace with all. Beloved, do not look for revenge but leave room for the wrath; for it is written, "Vengeance is mine, I will repay, says the Lord." Rather, "if your enemy is hungry, feed him; if he is thirsty, give him something to drink; for by so doing you will heap burning coals upon his head." Do not be conquered by evil but conquer evil with good.
(Romans 12:17-21 NAB)
