Proverbs 27:16-21 New King James Version (NKJV)

16. Whoever restrains her restrains the wind,And grasps oil with his right hand.

17. As iron sharpens iron,So a man sharpens the countenance of his friend.

18. Whoever keeps the fig tree will eat its fruit;So he who waits on his master will be honored.

19. As in water face reflects face,So a man’s heart reveals the man.

20. Hell and Destruction are never full;So the eyes of man are never satisfied.

21. The refining pot is for silver and the furnace for gold,And a man is valued by what others say of him.
