Proverbs 27:17-19

American Standard Version

¹⁷ Iron sharpeneth iron;
So a man sharpeneth the countenance of his friend.
¹⁸ Whoso keepeth the fig-tree shall eat the fruit thereof;
And he that regardeth his master shall be honored.
^19 [a]As in water face answereth to face,
So the heart of man to man.
