Repay no one evil for evil, but take thought for what is honest and proper and noble [aiming to be above reproach] in the sight of everyone. [Prov. 20:22.]
If possible, as far as it depends on you, live at peace with everyone.
Beloved, never avenge yourselves, but leave the way open for [God's] wrath; for it is written, Vengeance is Mine, I will repay (requite), says the Lord. [Deut. 32:35.]
But if your enemy is hungry, feed him; if he is thirsty, give him drink; for by so doing you will heap burning coals upon his head. [Prov. 25:21, 22.]
Do not let yourself be overcome by evil, but overcome (master) evil with good.
