Proverbs 27:17-23

¹⁷Iron sharpeneth iron; so a man sharpeneth the countenance of his friend.

¹⁸He that keepeth the fig-tree shall eat the fruit of it: so he that waiteth on his master shall be honored.

¹⁹As in water face answereth to face, so the heart of man to man.

²⁰Hell and destruction are never full; so the eyes of man are never satisfied.

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

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

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