19 Do not take revenge, dear fiends, but leave room for God's wrath. For it is written, "Vengeance belongs to me. I will pay them back, declares the Lord."20 But "if your enemy is hungry, feed him. For if he is thirsty, give him a drink. If you do this, you will pile burning coals on his head."21 Do not be conquered by evil, but conquer evil with good.
