“And it had a wall, great and high, having twelve gates, and at the gates twelve messengers, and names written on them, which are [the names] of the twelve tribes of the sons of Israel — three gates on the east, and three gates on the north, and three gates on the south, and three gates on the west; and the wall of the city had twelve foundations, and on them names of the twelve apostles of the Lamb.” — Revelation 21:12-14
“And the foundations of the wall of the city have been adorned with every precious stone: the first foundation jasper, the second sapphire, the third chalcedony, the fourth emerald, the fifth sardonyx, the sixth carnelian, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh jacinth, the twelfth amethyst.” — Revelation 21:19-20
All glory belongs to the Father alone.
