Ecclesiastes 10:1-3

¹Dead flies cause the ointment of the apothecary to send forth an offensive odor: so doth a little folly him that is in reputation for wisdom and honor.

²A wise man's heart is at his right hand; but a fool's heart is at his left.

³Also, when he that is a fool walketh by the way, his wisdom faileth him , and he saith to every one that he is a fool.
