“Therefore 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.”
King James Version (KJV)
12:20 Feed him - With your own hand: if it be needful, even put bread into his mouth. Heap coals of fire upon his head - That part which is most sensible. So artists melt the sullen ore of lead, By heaping coals of fire upon its head; In the kind warmth the metal learns to glow, And pure from dross the silver runs below. #Prov 25:21|, &c.
Ro 12:20 If thine enemy hunger, feed him. This is the spirit of Christ's command, to return good for evil. Compare Pr 25:21,23. In so doing thou shalt heap coals of fire on his head. Thou wilt by this kindness most readily subdue him, and make him feel most keenly the wrong he has done.
