Proverbs 25:4-5; Proverbs 25:21-22
Remove the dross from the silver, and a vessel will come out for the refiner.
Remove the wicked from the king's presence, and his throne will be established in righteousness.
If your enemies are starving, feed them some bread; if they are thirsty, give them water to drink.
By doing this, you will heap burning coals on their heads, and the LORD will reward you.
