5 In just the same way the tongue is a very small part of the body, but it makes great boasts! Think how a big forest can be set on fire by a very small flame! 6 And the tongue is a fire! The tongue is a world of evil among the parts of the body. It disgraces all you are as a person, and can burn down the whole of your life, since it is set on fire by Gehenna.3:6. Gehenna: the trash dump outside of Jerusalem where fires were used to burn the trash. The word is used symbolically as the endpoint for the wicked. See note on Matthew 5:22.
