Romans 12:17-19
17 Do not repay anyone evil for evil; be concerned for what is noble in the sight of all.
18 If possible, on your part, live at peace with all.
19 Beloved, do not look for revenge but leave room for the wrath; for it is written, "Vengeance is mine, I will repay, says the Lord."
1 Thessalonians 5:15
15 See that no one returns evil for evil; rather, always seek what is good (both) for each other and for all.
1 Peter 2:21-23
21 For to this you have been called, because Christ also suffered for you, leaving you an example that you should follow in his footsteps.
22 "He committed no sin, and no deceit was found in his mouth."
23 When he was insulted, he returned no insult; when he suffered, he did not threaten; instead, he handed himself over to the one who judges justly.
