Ecclesiastes 10:10-16

¹⁰If the axe-head should fall off, then the man troubles his countenance, and he must put forth more strength: and in that case skill is of no advantage to a man.

¹¹If a serpent bite when there is no charmer's whisper, then there is no advantage to the charmer.

¹²The words of a wise mouth are gracious: but the lips of a fool will swallow him up.

¹³The beginning of the words of his mouth is folly: and the end of his talk mischievous madness.

¹⁴A fool moreover multiplies words: man knows not what has been, nor what will be: who shall tell him what will come after him?

¹⁵The labour of fools will afflict them, as that of one who knows not to go to the city.

¹⁶Woe to you, O city, whose king is young, and your princes eat in the morning!
