10If iron is folded again, and it is not as before, but is made blunt, it shall be made sharp with much travail; and wisdom shall follow after busyness.
11If a serpent biteth, it biteth in silence; he that backbiteth privily, hath nothing less than it.
12The words of the mouth of a wise man be grace; and the lips of an unwise man shall cast him down.
13The beginning of his words is folly; and the last thing of his mouth is the worst error.
