Ecclesiastes 10:11-14 KJV

"Surely the serpent will bite without enchantment; and a babbler is no better. The words of a wise man’s mouth are gracious; but the lips of a fool will swallow up himself. The beginning of the words of his mouth is foolishness: and the end of his talk is mischievous madness. A fool also is full of words: a man cannot tell what shall be; and what shall be after him, who can tell him?"
