^2 (A)All of us often make mistakes. But if a person never makes a mistake in what he says, he is perfect and is also able to control his whole being. ³ We put a bit into the mouth of a horse to make it obey us, and we are able to make it go where we want. ⁴ Or think of a ship: big as it is and driven by such strong winds, it can be steered by a very small rudder, and it goes wherever the pilot wants it to go.
