James 3:1

Not many of you should become teachers, my brothers, because you know that we who teach will be judged more strictly.

² We all stumble in many ways. If anyone is never at fault in what he says, he is a perfect man, able to control his whole body.

³ When we put bits into the mouths of horses to make them obey us, we can guide the whole animal.
