Ecclesiastes 10:1-11

Dead flies cause the ointment of the apothecary to send forth a stinking savour: so doth a little folly him that is in reputation for wisdom and honour. A wise man's heart is at his right hand; but a fool's heart at his left. Yea also, 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. If the spirit of the ruler rise up against thee, leave not thy place; for yielding pacifieth great offences. There is an evil which I have seen under the sun, as an error which proceedeth from the ruler: folly is set in great dignity, and the rich sit in low place. I have seen servants upon horses, and princes walking as servants upon the earth. He that diggeth a pit shall fall into it; and whoso breaketh an hedge, a serpent shall bite him. Whoso removeth stones shall be hurt therewith; and he that cleaveth wood shall be endangered thereby. If the iron be blunt, and he do not whet the edge, then must he put to more strength: but wisdom is profitable to direct. Surely the serpent will bite without enchantment; and a babbler is no better.
