Ecclesiastes 10
11 Ref Surely the serpent will bite without enchantment; and a babbler is no better.
12 Ref The words of a wise man's mouth are gracious; but the lips of a fool will swallow up himself.
13 Ref The beginning of the words of his mouth is foolishness: and the end of his talk is mischievous madness.
14 Ref A fool also is full of words: a man cannot tell what shall be; and what shall be after him, who can tell him?
