Then came one of the seven angels who had the seven bowls full of the seven last plagues, and spoke to me, saying, "Come, I will show you the Bride, the wife of the Lamb." And in the Spirit he carried me away to a great, high mountain, and showed me the holy city Jerusalem coming down out of heaven from God, having the glory of God, its radiance like a most rare jewel, like a jasper, clear as crystal. It had a great, high wall, with twelve gates, and at the gates twelve angels, and on the gates the names of the twelve tribes of the sons of Israel were inscribed; on the east three gates, on the north three gates, on the south three gates, and on the west three gates. And the wall of the city had twelve foundations, and on them the twelve names of the twelve apostles of the Lamb. And he who talked to me had a measuring rod of gold to measure the city and its gates and walls.
The city lies foursquare, its length the same as its breadth; and he measured the city with his rod, twelve thousand stadia; its length and breadth and height are equal. He also measured its wall, a hundred and forty-four cubits by a man's measure, that is, an angel's. The wall was built of jasper, while the city was pure gold, clear as glass. The foundations of the wall of the city were adorned with every jewel; the first was jasper, the second sapphire, the third agate, the fourth emerald, the fifth onyx, the sixth carnelian, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh jacinth, the twelfth amethyst. And the twelve gates were twelve pearls, each of the gates made of a single pearl, and the street of the city was pure gold, transparent as glass.
