James 3:5-6, 8-9

So it is with the tongue: small as it is, it can boast about great things. Just think how large a forest can be set on fire by a tiny flame! And the tongue is like a fire. It is a world of wrong, occupying its place in our bodies and spreading evil through our whole being. It sets on fire the entire course of our existence with the fire that comes to it from hell itself.

But no one has ever been able to tame the tongue. It is evil and uncontrollable, full of deadly poison. We use it to give thanks to our Lord and Father and also to curse other people, who are created in the likeness of God.
