Revelation 21:10-25 (New International Version)
10And 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. 11It shone with the glory of God, and its brilliance was like that of a very precious jewel, like a jasper, clear as crystal. 12It had a great, high wall with twelve gates, and with twelve angels at the gates. On the gates were written the names of the twelve tribes of Israel. 13There were three gates on the east, three on the north, three on the south and three on the west. 14The wall of the city had twelve foundations, and on them were the names of the twelve apostles of the Lamb.
15The angel who talked with me had a measuring rod of gold to measure the city, its gates and its walls. 16The city was laid out like a square, as long as it was wide. He measured the city with the rod and found it to be 12,000 stadia in length, and as wide and high as it is long. 17He measured its wall and it was 144 cubits thick, by man's measurement, which the angel was using. 18The wall was made of jasper, and the city of pure gold, as pure as glass. 19The foundations of the city walls were decorated with every kind of precious stone. The first foundation was jasper, the second sapphire, the third chalcedony, the fourth emerald, 20the fifth sardonyx, the sixth carnelian, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh jacinth, and the twelfth amethyst.21The twelve gates were twelve pearls, each gate made of a single pearl. The great street of the city was of pure gold, like transparent glass.
22I did not see a temple in the city, because the Lord God Almighty and the Lamb are its temple. 23The city does not need the sun or the moon to shine on it, for the glory of God gives it light, and the Lamb is its lamp. 24The nations will walk by its light, and the kings of the earth will bring their splendor into it. 25On no day will its gates ever be shut, for there will be no night there.
