“Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, says the Lord.
“Therefore if your enemy hungers, feed him; if he thirsts, give him drink: for in so doing you shall heap coals of fire on his head.
“Be not overcome of evil, but overcome evil with good.”
