Romans 12:19-21

Beloved, never avenge yourselves, but leave it to the wrath of God; for it is written, "Vengeance is mine, I will repay, says the Lord." No, if your enemy is hungry, feed him; if he is thirsty, give him drink; for by so doing you will heap burning coals upon his head. Do not be overcome by evil, but overcome evil with good. Romans 12:19-21
