Proverbs 27:20-22

²⁰Hell and destruction are not filled; so also are the eyes of men insatiable. He that fixes his eye is an abomination to the Lord; and the uninstructed do not restrain their tongue.

²¹Fire is the trial for silver and gold; and a man is tried by the mouth of them that praise him. The heart of the transgressor seeks after mischiefs; but an upright heart seeks knowledge.

²²Though you scourge a fool, disgracing him in the midst of the council, you will still in no wise remove his folly from him.
