James 3:1–5
[1] Not many of you should become teachers, my brothers, for you know that we who teach will be judged with greater strictness. [2] For we all stumble in many ways. And if anyone does not stumble in what he says, he is a perfect man, able also to bridle his whole body. [3] If we put bits into the mouths of horses so that they obey us, we guide their whole bodies as well. [4] Look at the ships also: though they are so large and are driven by strong winds, they are guided by a very small rudder wherever the will of the pilot directs. [5] So also the tongue is a small member, yet it boasts of great things.
How great a forest is set ablaze by such a small fire! (ESV)
