11If the serpent bites before being charmed, there is no benefit for the charmer. 12Words from the mouth of a wise person are gracious, while the lips of a fool consume him; 13the beginning of his talking is foolishness, and the end of it is evil insanity. 14Yet the fool multiplies words. No person knows what will happen, and who can tell him what will come after him? 15The labor of a fool makes him so weary that he does not even know how to go to a city.
