8 He that diggeth a gumatz (pit) shall fall into it; and whoso breaketh through a wall, a nachash shall bite him.
9 Whoso pulleth out avanim (stones) may be hurt therewith; and he that cleaveth wood may be endangered thereby.
10 If the barzel (iron [of the axe]) be blunt, and he do not whet the edge, then must more strength be marshalled; but chochmah brings success.
11 If the nachash will bite before it is charmed, there is no use in a charmer.
12 The words of a chacham's mouth are chen (gracious); but the lips of a kesil will swallow up himself.
13 The beginning of the words of his mouth is sichlut; and the end of his talk is holelot ra'ah.
14 A kesil also is full of devarim; haAdam has no da'as of what shall be, and what shall be after him, who can tell him?
