Proverbs 27:21-23

Authorized (King James) Version

²¹ As the fining pot for silver, and the furnace for gold;
so is a man to his praise.

²² Though thou shouldest bray a fool in a mortar among wheat with a pestle,
yet will not his foolishness depart from him.

²³ Be thou diligent to know the state of thy flocks,
and look well to thy herds.
