James 3:5 in the King James Version
Even so the tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth!
Context
4 Behold, the ships also, though they are so big and are driven by fierce winds, are yet guided by a very small rudder, wherever the pilot desires.
5 So the tongue is also a little member, and boasts great things. See how a small fire can spread to a large forest!
6 And the tongue is a fire. The world of iniquity among our members is the tongue, which defiles the whole body, and sets on fire the course of nature, and is set on fire by Gehenna.
