9. One who quarries stones may be injured by them;one who splits logs may be endangered by them.
10. If an iron axhead is blunt and a workman does not sharpen its edge,he must exert a great deal of effort;so wisdom has the advantage of giving success.

12. The words of a wise person win him favor,but the words of a fool are self-destructive.
13. At the beginning his words are foolishand at the end his talk is wicked madness,

15. The toil of a stupid fool wears him out,because he does not even know the way to the city.
