Ecclesiastes 10:3-13

³When a fool walks down a road, his thinking is deficient, proving to everyone he is a fool.

⁴If the emotions of a ruler rise up against you, do not leave your work. Calm can quiet down great outrage.

⁵There is an evil that I have seen under the sun, a kind of error that comes from a ruler:

⁶Fools are given leadership positions, while successful men are given low positions.

⁷I have seen slaves riding horses, and successful men walking like slaves on the ground.

⁸Anyone who digs a pit can fall into it, and whenever someone breaks down a wall, a snake can bite him.

⁹Whoever cuts out stones can be hurt by them, and the man who chops wood is endangered by it.

¹⁰If an iron blade is dull, and a man does not sharpen it, then he must use more strength, but wisdom provides an advantage for success.

¹¹If a snake bites before it is charmed, then there is no advantage for the charmer.

¹²The words of a wise man's mouth are gracious, but the lips of a fool consume him.

¹³As words begin to flow from a fool's mouth, foolishness comes out, and at the end his mouth flows with wicked madness.
