Ecclesiastes 10:8-15

⁸He who digs a pit may fall into it; and whoever breaks through a wall may be bitten by a snake.

⁹Whoever carves out stones may be injured by them. Whoever splits wood may be endangered by it.

¹⁰If the ax is blunt, and one doesn’t sharpen the edge, then he must use more strength; but skill brings success.

¹¹If the snake bites before it is charmed, then is there no profit for the charmer’s tongue.

¹²The words of a wise man’s mouth are gracious; but a fool is swallowed by his own lips.

¹³The beginning of the words of his mouth is foolishness; and the end of his talk is mischievous madness.

¹⁴A fool also multiplies words. Man doesn’t know what will be; and that which will be after him, who can tell him?

¹⁵The labor of fools wearies every one of them; for he doesn’t know how to go to the city.
