It had a great high wall, in which were twelve gates; and at these gates there were twelve angels, and there were names inscribed on the gates, the names of the twelve tribes of the Israelites. 'There were three gates on the east, three gates on the north, three gates on the south, and three gates on the west.' read more.
The wall of the City had twelve foundation stones, on which were the twelve names of the twelve Apostles of the Lamb. And the angel who was speaking to me had as a measure a gold rod, with which to measure the City and its gates and its wall. The City is square; the length and the breadth are the same. The angel measured with his rod; it was twelve hundred miles; its length, and breadth, and height are equal. Then he measured the wall; it was two hundred and eighty-eight feet, as men measure, that is as the angel measured. The material of the wall of the City was jasper, and the City was built of pure gold, which shone like clear glass. The foundations of the wall of the City were ornamented with every kind of precious stone. The first foundation stone was a jasper; the second a sapphire; the third a chalcedony; the fourth an emerald; the fifth a sardonyx; the sixth a carnelian; the seventh a chrysolite; the eighth a beryl; the ninth a topaz; the tenth a chrysoprase; the eleventh a hyacinth; and the twelfth an amethyst.
