Romans 12:19-20
Romans 12:19-20 NCV
My friends, do not try to punish others when they wrong you, but wait for God to punish them with his anger. It is written: “I will punish those who do wrong; I will repay them,” says the Lord. But you should do this: “If your enemy is hungry, feed him; if he is thirsty, give him a drink. Doing this will be like pouring burning coals on his head.”
