'Shut' in the Bible

saying, The prison-house we found shut in all safety, and the keepers standing at the doors: but when we had opened, we found no man within.

And all the city was moved, and the people ran together; and they laid hold on Paul, and dragged him out of the temple: and straightway the doors were shut.

And this I also did in Jerusalem: and I both shut up many of the saints in prisons, having received authority from the chief priests, and when they were put to death I gave my vote against them.
