James 3:2, 5-6

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.

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.
