² All of us make a lot of mistakes. If someone doesn’t make any mistakes when he speaks, he would be perfect. He would be able to control everything he does. ³ We put bits in the mouths of horses to make them obey us, and we have control over everything they do. ⁴ The same thing is true for ships. They are very big and are driven by strong winds. Yet, by using small rudders, pilots steer ships wherever they want them to go.
