Revelation 21:14-20

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. 19The foundations of the city walls were adorned 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.
