'Door' in the Bible

So Peter [said] to her, "How [is it] that it was agreed by you [two] to test the Spirit of the Lord? Behold, the feet of those who buried your husband [are] at the door, and they will carry you out!"

Now when Herod was about to bring him [out], on that [very] night Peter was sleeping between two soldiers, bound with two chains, and guards before the door were watching the prison.

And [when] he knocked at the door of the gateway, a female slave {named} Rhoda came up to answer.

But Peter was continuing to knock, and [when they] opened [the door] they saw him and were astonished.

And [when they] arrived and called the church together, they reported all that God had done with them, and that he had opened a door of faith for the Gentiles.

And leaving there, he entered into the house of someone {named} Titius Justus, a worshiper of God whose house was next door to the synagogue.
