Proverbs 27:21-23

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.

²³Do you thoroughly know the number of your flock, and pay attention to your herds.
