Romans 12:17-20

Do not repay anyone evil for evil. Try to do what is honorable in everyone’s eyes. If possible, on your part, live at peace with everyone. Friends, do not avenge yourselves; instead, leave room for His wrath. For 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.
