Boast not thyself of to morrow; for thou knowest not what a day may bring forth.

Let another man praise thee, and not thine own mouth; a stranger, and not thine own lips.

Open rebuke is better than secret love.

Faithful are the wounds of a friend; but the kisses of an enemy are deceitful.

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

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

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