Matthew 5:39, 44

However, I say to you, don’t repay an evil act with another evil act. But whoever insults you by slapping you on the right cheek, turn the other to him as well.

However, I say to you, love your enemy, bless the one who curses you, do something wonderful for the one who hates you, and respond to the very ones who persecute you by praying for them.
