Read James 3:5 Using Other Translations
Even so the tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth!
So also the tongue is a small member, yet it boasts of great things. How great a forest is set ablaze by such a small fire!
In the same way, the tongue is a small thing that makes grand speeches. But a tiny spark can set a great forest on fire.
