Ecclesiastes 10:1-6

Dead flies cause the oil of the perfumer to send forth an evil odor; so doth a little folly outweigh wisdom and honor. A wise man’s heart is at his right hand; but a fool’s heart at his left. Yea also, when the fool walketh by the way, his understanding faileth him, and he saith to every one that he is a fool. If the spirit of the ruler rise up against thee, leave not thy place; for gentleness allayeth great offences. There is an evil which I have seen under the sun, as it were an error which proceedeth from the ruler: folly is set in great dignity, and the rich sit in a low place.
