Proverbs 25:4-5; Proverbs 25:21-22
Take away the dross from the silver, and there cometh forth a vessel for the refiner:
take away the wicked from before 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 Jehovah shall reward thee.
