'Dumb' in the Bible

And now you will be dumb and unable to speak until the day when this has taken place; because you did not believe my words--words which will be fulfilled at their appointed time."

When, however, he came out, he was unable to speak to them; and they knew that he must have seen a vision in the Sanctuary; but he kept making signs to them and continued dumb.

On once occasion He was expelling a dumb demon; and when the demon was gone out the dumb man could speak, and the people were astonished.
