Ecclesiastes 10:3, 12-14

Even when a fool walks along the way, He lacks wisdom, And he shows everyone that he is a fool.

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?
