Revelation 21:11-18

11shining with the glory of God. Its radiance was like a most precious jewel, like a jasper, as clear as crystal. 12The city had a great and high wall with twelve gates inscribed with the names of the twelve tribes of Israel, and twelve angels at the gates. 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 bearing the names of the twelve apostles of the Lamb.

15The angel who spoke with me had a golden measuring rod to measure the city and its gates and walls. 16The city lies foursquare, with its width the same as its length. And he measured the city with the rod, and all its dimensions were equal—12,000 stadia1 in length and width and height. 17And he measured its wall to be 144 cubits,2 by the human measure the angel was using.

18The wall was made of jasper, and the city itself of pure gold, as pure as glass.
