James 3:2-4

2For we all stumble in many ways. If someone does not stumble in speech, he is a perfect man, able to bridle the whole body as well.

3And if we put bits into the mouths of horses to make them obey us, we guide their whole body as well.

4See also the ships—though they are so large and are driven by strong winds, they are steered by a very small rudder wherever the will of the pilot directs.
