Proverbs 25:20-22

²⁰As vinegar is bad for a sore, so trouble befalling the body afflicts the heart. As a moth in a garment, and a worm in wood, so the grief of a man hurts the heart.

²¹If your enemy hunger, feed him; if he thirst, give him drink;

²²for so doing you shall heap coals of fire upon his head, and the Lord shall reward you with good.
