Proverbs 25:4-5; Proverbs 25:21-22
Take away the dross from the silver, and there shall come forth a vessel for the refiner.
Take away the wicked from the presence of the king, and his throne shall be established in righteousness.
If thine enemy be hungry, give him bread to eat; and if he be thirsty, give him water to drink;
for thou shalt heap coals of fire upon his head, and the LORD shall reward thee.
