10:8 One who digs a pit may fall into it,
and one who breaks through a wall may be bitten by a snake.
10:9 One who quarries stones may be injured by them;
one who splits logs may be endangered by them.
10:10 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.
10:11 If the snake should bite before it is charmed,
the snake charmer is in trouble.
