Romans 12:18-21

If possible, as far as it depends on you, live at peace with everyone. Friends, do not avenge yourselves; instead, leave room for God’s wrath, because it is written, Vengeance belongs to me; I will repay, says the Lord. But If your enemy is hungry, feed him. If he is thirsty, give him something to drink. For in so doing you will be heaping fiery coals on his head. Do not be conquered by evil, but conquer evil with good.
