Romans 12:17, 19

Never repay anyone evil for evil. Take thought for what is right and gracious and proper in the sight of everyone. [Prov 20:22]

Beloved, never avenge yourselves, but leave the way open for God’s wrath [and His judicial righteousness]; for it is written [in Scripture], “VENGEANCE IS MINE, I WILL REPAY,” says the Lord. [Deut 32:35]
