'Shut' in the Bible

And I went to the house of Shemaiah, the son of Delaiah, the son of Mehetabel, who was shut up; and he said, Let us have a meeting in the house of God, inside the Temple, and let the doors be shut: for they will come to put you to death; truly, in the night they will come to put you to death.

And I said to them, Do not let the doors of Jerusalem be open till the sun is high; and while the watchmen are in their places, let the doors be shut and locked: and let the people of Jerusalem be put on watch, every one in his watch, opposite his house.

And so, when the streets of Jerusalem were getting dark before the Sabbath, I gave orders for the doors to be shut and not to be open again till after the Sabbath: and I put some of my servants by the door so that nothing might be taken in on the Sabbath day.
