Ecclesiastes 10:1-10

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. I have seen servants upon horses, and princes walking like servants upon the earth. He that diggeth a pit shall fall into it; and whoso breaketh through a wall, a serpent shall bite him. Whoso heweth out stones shall be hurt therewith; and he that cleaveth wood is endangered thereby. If the iron be blunt, and one do not whet the edge, then must he put to more strength: but wisdom is profitable to direct.
