The wall of the city had twelve foundations, and on them were the names of the twelve apostles of the Lamb.
The angel who talked with me had a measuring rod of gold to measure the city, its gates and its walls.
The 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.
The angel measured the wall using human measurement, and it was 144 cubits thick.
The wall was made of jasper, and the city of pure gold, as pure as glass.
The foundations of the city walls were decorated with every kind of precious stone. The first foundation was jasper, the second sapphire, the third agate, the fourth emerald,
the fifth onyx, the sixth ruby, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth turquoise, the eleventh jacinth, and the twelfth amethyst.
The twelve gates were twelve pearls, each gate made of a single pearl. The great street of the city was of gold, as pure as transparent glass.
