Proverbs 25:4-5; Proverbs 25:21-22
Take away the dross from the silver, and the smith has material for a vessel;
take away the wicked from the presence of the king, and his throne will be established in righteousness.
If your enemy is hungry, give him bread to eat; and if he is thirsty, give him water to drink;
for you will heap coals of fire on his head, and the LORD will reward you.
