'Shut' in the Bible

"To the messenger of the church in Philadelphia, write: "The one who is holy, who is true, who has the key of David, who opens a door that no one can shut, and who shuts a door that no one can open, "says this:

"I know what you've been doing. Look! I have put in front of you an open door that no one can shut. You have only a little strength, but you have obeyed my word and have not denied my name.

Its gates will never be shut at the end of the day because there will be no night there.
