7 I have seen servants upon horses, and princes walking like servants upon the earth.
8 He that diggeth a pit shall fall into it; and whoso breaketh through a wall, a serpent shall bite him.
9 Whoso heweth out stones shall be hurt therewith; `and' he that cleaveth wood is endangered thereby.
10 If the iron be blunt, and one do not whet the edge, then must he put to more strength: but wisdom is profitable to direct.
11 If the serpent bite before it is charmed, then is there no advantage in the charmer.
