'Shut' in the Bible

Why are my words not clear to you? It is because your ears are shut to my teaching.

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:

At evening on that day, the first day of the week, when, for fear of the Jews, the doors were shut where the disciples were, Jesus came among them and said to them, May peace be with you!

And after eight days, his disciples were again in the house and Thomas was with them. Though the doors were shut, Jesus came, and taking his place in the middle of them, he said, May peace be with you!
