'Holy City' in the Bible

And the court which is without the temple leave without, and measure it not; for it hath been given unto the nations: and the holy city shall they tread under foot forty and two months.

And I saw the holy city, new Jerusalem, coming down out of heaven of God, made ready as a bride adorned for her husband.

And he carried me away in the Spirit to a mountain great and high, and showed me the holy city Jerusalem, coming down out of heaven from God,

and if any man shall take away from the words of the book of this prophecy, God shall take away his part from the tree of life, and out of the holy city, which are written in this book.
