Then I saw an angel descending from heaven, holding in his hand the key to the abyss and a huge chain.

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.
