Ecclesiastes 10:1-10

Dead flies can make even perfume stink. In the same way, a little foolishness can spoil wisdom. The heart of the wise leads to right, but the heart of a fool leads to wrong. Even in the way fools walk along the road, they show they are not wise; they show everyone how stupid they are. Don’t leave your job just because your boss is angry with you. Remaining calm solves great problems. There is something else wrong that happens here on earth. It is the kind of mistake rulers make: Fools are given important positions while gifted people are given lower ones; I have seen servants ride horses while princes walk like servants on foot. Anyone who digs a pit might fall into it; anyone who knocks down a wall might be bitten by a snake; anyone who moves boulders might be hurt by them; and anyone who cuts logs might be harmed by them. A dull ax means harder work. Being wise will make it easier.
