'Door' in the Bible

But you, when you pray, go into your inner room, close your door and pray to your Father who is in secret, and your Father who sees what is done in secret will reward you.

so, you too, when you see all these things, recognize that He is near, right at the door.

And while they were going away to make the purchase, the bridegroom came, and those who were ready went in with him to the wedding feast; and the door was shut.
