James 3:4-6

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.
