Ecclesiastes 10:11-14

A serpent may bite when it is not charmed; The babbler is no different. The words of a wise man’s mouth are gracious, But the lips of a fool shall swallow him up; The words of his mouth begin with foolishness, And the end of his talk is raving madness. A fool also multiplies words. No man knows what is to be; Who can tell him what will be after him?
