If thine enemy hunger feed him: if he thirst, give him drink: fo in so doing thou shalt heap coals of fire on his head. Be not overcome of evil, but overcome evil with good. Rom. 12:20, 21
Thus artists melt the sullen ore of lead,
With heaping coals of fire upon its head;
In the kind warmth the metal learns to glow,
And loose from dross the silver runs below.
