'Shut' in the Bible

Why do you misunderstand what I am saying? It is because [your spiritual ears are deaf and] you are unable to hear [the truth of] My word.

His answer was: I have said it before, but your ears were shut: why would you have me say it again? is it your desire to become his disciples?

However, a number even of the rulers had belief in him, but because of the Pharisees they did not say so openly for fear that they might be shut out from the Synagogue:

Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you.

And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you.
