10 If 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.
11 If a serpent biteth, it biteth in silence; he that backbiteth privily, hath nothing less than it, (or he who privately, or secretly, backbiteth someone is no better).
12 The words of the mouth of a wise man be grace; and the lips of an unwise man shall cast him down. (The words out of the mouth of a wise person bring him favour; but the lips of an unwise person shall bring him down.)
13 The beginning of his words is folly; and the last thing of his mouth is the worst error. (His words begin with foolishness; and the last thing out of his mouth is the worst error of all.)
14 A fool multiplieth words; a man knoweth not, what was before him, and who may show to him that, that shall come after him? (or and who can show him what shall come after him?)
15 The travail of fools shall torment them, that know not how to go into the city. (Fools work themselves to exhaustion, yet they do not even know how to go into the city.)
