Romans 12:18-19; Romans 12:14

18 If it is possible, as much as depends on you, live peaceably with all men. 19 Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, "Vengeance is Mine, I will repay," says the Lord.
14 Bless those who persecute you; bless and do not curse.
