Romans 12:14, 17-21

Bless those who persecute you. Don’t curse them; pray that God will bless them.

Never pay back evil with more evil. Do things in such a way that everyone can see you are honorable. Do all that you can to live in peace with everyone. Dear friends, never take revenge. Leave that to the righteous anger of God. For the Scriptures say, “I will take revenge; I will pay them back,” says the LORD. Instead, “If your enemies are hungry, feed them. If they are thirsty, give them something to drink. In doing this, you will heap burning coals of shame on their heads.” Don’t let evil conquer you, but conquer evil by doing good.
