'Door' in the Bible

But whenever you pray, go into your room, close the door, and pray to your Father in secret. And your Father, who sees in secret, will reward you.

"Ask and it will be given to you; seek and you will find; knock and the door will be opened for you.

For everyone who asks receives, and the one who seeks finds, and to the one who knocks, the door will be opened.

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