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.

^21aThe heart of the transgressor seeks after mischiefs; but an upright heart seeks knowledge.

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

²³Do thou thoroughly know the number of thy flock, and pay attention to thine herds.
