Ecclesiastes 10:4-10

4If the anger of the ruler flares up against you, do not resign from your position, for a calm response can undo great offenses.

5I have seen another misfortune on the earth: It is an error a ruler makes.

6Fools are placed in many positions of authority, while wealthy men sit in lowly positions.

7I have seen slaves on horseback and princes walking on foot like slaves.

8One who digs a pit may fall into it, and one who breaks through a wall may be bitten by a snake.

9One who quarries stones may be injured by them; one who splits logs may be endangered by them.

10If an iron axhead is blunt and a workman does not sharpen its edge, he must exert a great deal of effort; so wisdom has the advantage of giving success.
