Overcome Evil with Good
Rather, if your enemy is hungry, feed him; if he is thirsty, give him a drink; for in doing this you will be heaping burning coals on his head. Do not be overcome by evil, but overcome evil with good.
[Rom 12:20-21 NET]
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.
