Ecclesiastes 10:11-14

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?
