Proverbs 27:20-24

Hell and destruction are never full; so the eyes of man are never satisfied.

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

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

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

For riches are not for ever: and doth the crown endure to every generation?
