'Holy City' in the Bible

But do not measure the outer courtyard of the temple; leave it out, because it has been given to the Gentiles, and they will trample on the holy city for forty-two months.

And I saw the holy city -- the new Jerusalem -- descending out of heaven from God, made ready like a bride adorned for her husband.

So he took me away in the Spirit to a huge, majestic mountain and showed me the holy city, Jerusalem, descending out of heaven from God.

And if anyone takes away from the words of this book of prophecy, God will take away his share in the tree of life and in the holy city that are described in this book.
