Romans 12:18

16Be of the same mind one toward another. Mind not high things, but condescend to men of low estate. Be not wise in your own conceits.

17Recompense to no man evil for evil. Provide things honest in the sight of all men.

18If it be possible, as much as lieth in you, live peaceably with all men.

19Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord.

20Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head.
