Romans 12:17-21

Thomson(i) 17 Render to none evil for evil. Be provident in regard to things good in the sight of all men. 18 If possible, that is, as far as in your power, be at peace with all men. 19 Beloved, avenge not yourselves, but give place to the wrath; for it is written, "Vengeance is mine; I will requite, saith the Lord." 20 Therefore if thine enemy hunger feed him; if he be thirsty, give him drink; for by doing so thou wilt use the means to melt him. 21 Be not overcome by evil; but overcome evil with good.
