Ecclesiastes 10:12-14

¹²The words of a wise man's mouth are gracious; but the lips of a fool swallow up himself.

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

¹⁴And the fool multiplieth words: yet man knoweth not what shall be; and what shall be after him, who will tell him?
