'Door' in the Bible

But whenever you pray, enter into your inner room and shut your door [and] pray to your Father who is in secret, and your Father who sees in secret will reward you.

So also you, when you see all these [things], know that he is near, at the door.

But [while] they had gone away to buy [it] the bridegroom arrived, and those who were ready went inside with him to the wedding celebration, and the door was shut.

And later the other virgins came also, saying, 'Lord, lord, open [the door] for us!'
