Romans 12:19-21
Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, 'Vengeance is Mine, I will repay,' says the Lord. Therefore,
'If your enemy is hungry, feed him;
If he is thirsty, give him a drink;
For in so doing you will heap coals of fire on his head.'
Do not be overcome by evil, but overcome evil with good.
