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 burning coals on his head, and the LORD will reward you.
