Ecclesiastes 10
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 multiplieth words: `yet' man knoweth not what shall be; and that which shall be after him, who can tell him?
