Ecclesiastes 10:1-3

Revised Geneva Translation

10 Dead flies cause stink and putrefy the ointment of the apothecary. So does a little folly him who is esteemed for wisdom, and for glory.

² The heart of a wise man is at his right hand. But the heart of a fool is at his left hand.

³ And even when the fool walks along the way, his wisdom fails. And he tells everyone that he is a fool.
