For in many things we all stumble. If any stumbleth not in word, the same is a perfect man, able to bridle the whole body also.
Now if we put the horses' bridles into their mouths that they may obey us, we turn about their whole body also.
Behold, the ships also, though they are so great and are driven by rough winds, are yet turned about by a very small rudder, whither the impulse of the steersman willeth.
So the tongue also is a little member, and boasteth great things. Behold, how much wood is kindled by how small a fire!
And the tongue is a fire: the world of iniquity among our members is the tongue, which defileth the whole body, and setteth on fire the wheel of nature, and is set on fire by hell.
