'There were three gates on the east, three gates on the north, three gates on the south, and three gates on the west.'
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.
The wall of the City had twelve foundation stones, on which were the twelve names of the twelve Apostles of the Lamb.
