Ecclesiastes 10:1-12

1 Dead flies cause the oil of the perfumer to send forth an evil odor; so does a little folly outweigh wisdom and honor.
2 A wise man's heart is at his right hand, but a fool's heart at his left.
3 Yes also, when the fool walks by the way, his understanding fails him, and he says to everyone that he is a fool.
4 If the spirit of the ruler rises up against you, don't leave your place; for gentleness lays great offenses to rest.
5 There is an evil which I have seen under the sun, the sort of error which proceeds from the ruler.
6 Folly is set in great dignity, and the rich sit in a low place.
7 I have seen servants on horses, and princes walking like servants on the eretz.
8 He who digs a pit may fall into it; and whoever breaks through a wall may be bitten by a snake.
9 Whoever carves out stones may be injured by them. Whoever splits wood may be endangered thereby.
10 If the ax is blunt, and one doesn't sharpen the edge, then he must use more strength; but skill brings success.
11 If the snake bites before it is charmed, then is there no profit for the charmer's tongue.
12 The words of a wise man's mouth are gracious; but a fool is swallowed by his own lips.
