Ecclesiastes 10:1-3

Young's Literal Translation

10 Dead flies cause a perfumer's perfume To send forth a stink; The precious by reason of wisdom -- By reason of honour -- a little folly!

² The heart of the wise [is] at his right hand, And the heart of a fool at his left.

³ And also, when he that is a fool Is walking in the way, his heart is lacking, And he hath said to every one, `He [is] a fool.'
