'Shut' in the Bible

Saying, The prison truly found we shut with all safety, and the keepers standing without before 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 took Paul, and drew him out of the temple: and forthwith the doors were shut.

Which thing I also did in Jerusalem: and many of the saints did I shut up in prison, having received authority from the chief priests; and when they were put to death, I gave my voice against them.
