12 Words from a wise man's mouth are gracious, but a fool is consumed by his own lips.
13-14 At the beginning his words are folly; at the end they are wicked madness-and the fool multiplies words. No one knows what is coming— who can tell him what will happen after him?
15 A fool's work wearies him; he does not know the way to town.
Ecclesiastes 10:12-15 (New International Version)
