Revelation 21:10-21

He carried me away in the realm of the Spirit to the top of a great, high mountain. There he showed me the holy city, Jerusalem, descending out of heaven from God. It was infused with the glory of God, and its radiance was like that of a very rare jewel, like a jasper, clear as crystal. It had a massive, high wall with twelve gates, and each gate had an angel. Each gate had written upon it a name of one of the twelve tribes of Israel—three gates on the east, three gates on the north, three gates on the south, and three gates on the west. The city wall had twelve foundations, and on them were the names of the twelve apostles of the Lamb. The angel who spoke with me had a gold measuring rod to measure the city, its gates and walls. The city was laid out in a perfect square; its length, width, and height were equal. So he measured the city with his rod, and it was 12,000 stadia, with equal dimensions for its width, length, and height. He also measured the wall at 144 cubits, according to the measure of a man, which is angelic. The city was pure gold, clear as crystal, and its wall was made of jasper. The twelve foundations of the wall were adorned with every kind of precious stone—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 turquoise, and the twelfth amethyst. The twelve gates are twelve pearls—each gate made of one pearl. And the street of the city was pure gold, clear as crystal.
