Proverbs 27:17 (KJV)
Context Reading
15A continual dropping in a very rainy day and a contentious woman are alike. 16Whosoever hideth her hideth the wind, and the ointment of his right hand, which bewrayeth itself. 17Iron sharpeneth iron; so a man sharpeneth the countenance of his friend. 18Whoso keepeth the fig tree shall eat the fruit thereof: so he that waiteth on his master shall be honoured. 19As in water face answereth to face, so the heart of man to man.
