Ecclesiastes 10:12-14

¹²The words of the mouth of a wise man are grace: but the lips of a fool shall throw him down headlong.

¹³The beginning of his words is folly, and the end of his talk is a mischievous error.

¹⁴A fool multiplieth words. A man cannot tell what hath been before him: and what shall be after him, who can tell him?
