'Tongue' in the Bible

If someone thinks he is religious yet does not bridle his tongue, and so deceives his heart, his religion is futile.

So too the tongue is a small part of the body, yet it has great pretensions. Think how small a flame sets a huge forest ablaze.

And the tongue is a fire! The tongue represents the world of wrongdoing among the parts of our bodies. It pollutes the entire body and sets fire to the course of human existence -- and is set on fire by hell.

But no human being can subdue the tongue; it is a restless evil, full of deadly poison.
