Proverbs 27:19LXX

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 to face, so the heart of man to man.

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

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