Ecclesiastes 10:13-15

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