And the foundations of the wall of the city were adorned with all manner of precious stones. The first foundation was jasper: the second, sapphire: the third, a chalcedony: the fourth, an emerald:

“Tradition assures us that the heavenly Jerusalem that is above is built up of holy gems, and we know that the twelve gates of the heavenly city, which signify the wonderful beauty of the apostolic teaching, are compared with precious jewels. These priceless stones are described as possessing certain colors that are themselves precious, while the rest is left of an earthly substance. To say that the city of the saints is built of such jewels, even though it is a spiritual edifice, is a cogent symbol indeed. By the incomparable brilliance of the gems is understood the spotless and holy brilliance of the substance of the spirit.”

“The city which he says is squared, he says also is resplendent with gold and precious stones, and has a sacred street, and a river through the midst of it, and the tree of life on either side, bearing twelve manner of fruits throughout the twelve months; and that the light of the sun is not there, because the Lamb is the light of it; and that its gates were of single pearls; and that there were three gates on each of the four sides, and that they could not be shut. I say, in respect of the square city, he shows forth the united multitude of the saints, in whom the faith could by no means waver. As Noah is commanded to make the ark of squared beams, that it might resist the force of the deluge, by the precious stones he sets forth the holy men who cannot waver in persecution, who could not be moved either by the tempest of persecutors, or be dissolved from the true faith by the force of the rain, because they are associated of pure gold, of whom the city of the great King is adorned. Moreover, the streets set forth their hearts purified from all uncleanness, transparent with glowing light, that the Lord may justly walk up and down in them.”

“The fifth, sardonyx,.... Which is partly of the sardian, and partly of the onyx stone, which resembles a man's nail, from whence it has its name; it is reddish, bordering on white; it may be thought to answer to the onyx in the breastplate, on which was written the name of Joseph. The sixth, sardius; the same with the sardine stone, Rev 4:3 of a blood colour, and what is commonly called a cornelian: it is found in Sardinia, from whence it has its name, and in Bohemia and Silesia, though those of Babylon are the best. This was Reuben's stone. The seventh, chrysolite; a stone of a dusky green colour, with a cast of yellow; by its name it should have the colour of gold. Schroder says it is found in Bohemia, and that it is the same the moderns call the topaz. Some think it answers to "tarshish" in the breastplate, rendered "beryl", on which was the name of Asher. The eighth, beryl; a stone of a pale green colour, thought to be the diamond of the ancients: it may answer to the "ligure" in the breastplate, which the Targum on Sol 5:14 calls "birla", and had the name of Dan on it. The ninth, a topaz; a stone very hard and transparent, of a beautiful yellow, or gold colour: the topaz of Ethiopia was counted the best, Job 28:19. Some say it is so called from the island "Topazus"; on this stone Simeon's name was engraven. The tenth, a chrysoprasus; a stone of a green colour, inclining to that of gold, from whence it has its name; for this is the agate in the breastplate, which was Napthali's stone. The eleventh, a jacinth; or "hyacinth": a stone of a purple, or violet colour, from whence it has its name; though what the moderns so call is of a deep reddish yellow, pretty near a flame colour. Zabulon's stone was the diamond. The twelfth, an amethyst; a stone of a violet colour, bordering on purple: it has been thought a preservative from drunkenness, from whence it seems to have its name. On this stone was written the name of Gad. Agreeably to this account of John's, the Jews speak (n) of the tabernacle above being built on twelve precious stones; and sometimes they say (o), that the holy blessed God will found Jerusalem with ten kind of precious stones, and which they mention, and several of which are the same with these. (n) Zohar in Gen. fol. 17. 2. & in Exod. fol. 65. 4. (o) Abkath Rocel, p. 150. Vid. Zohar in Exod. fol. 96. 3.”

“The foundations of the wall - Does not this mean the foundations or thresholds of the gates? The gates represented the twelve tribes, Rev 21:12; and these foundations or thresholds, the twelve apostles, Rev 21:14. There was no entrance into the city but through those gates, and none through the gates but over these thresholds. The whole of the Mosaic dispensation was the preparation of the Gospel system: without it the Gospel would have no original; without the Gospel, it would have no reference nor proper object. Every part of the Gospel necessarily supposes the law and the prophets. They are the gates, it is the threshold; without the Gospel no person could enter through those gates. The doctrine of Christ crucified, preached by the apostles, gives a solid foundation to stand on; and we have an entrance into the holiest by the blood of Jesus, Heb 10:19, etc. And in reference to this we are said to be built on the Foundation of the Apostles and prophets, Jesus Christ himself being the chief corner stone, Eph 2:20. The first foundation was jasper - A stone very hard, some species of which are of a sea-green color; but it is generally a bright reddish brown. The second, sapphire - This is a stone of a fine blue color, next in hardness to the diamond. The third, a chalcedony - A genus of the semipellucid gems, of which there are four species: - 1. A bluish white; this is the most common sort. 2. The dull milky veined; this is of little worth. 3. The brownish black; the least beautiful of all. 4. The yellow and red; the most beautiful, as it is the most valuable of all. Hitherto this has been found only in the East Indies. The fourth, an emerald - This is of a bright green color without any mixture, and is one of the most beautiful of all the gems, The true oriental emerald as very scarce, and said to be found only in the kingdom of Cambay.”

“And--so Syriac, Coptic, and ANDREAS. But A, B, and Vulgate omit. Compare Rev 21:14 with this verse; also Isa 54:11. all manner of precious stones--Contrast Rev 18:12 as to the harlot, Babylon. These precious stones constituted the "foundations." chalcedony--agate from Chalcedon: semi-opaque, sky-blue, with stripes of other colors [ALFORD].”

“Jasper. This stone is green, and therefore signifies the unfading greenness of faith. Or jasper is the faith of the saints, not withering, but always persevering in the greenness of work. Sapphire. It is like a clear sky, which, struck by the rays of the sun, sends forth a burning brightness; and it signifies the loftiness of the hope of the saints, whose conversation is in the heavens, who also, renewed by the true sun, seek eternal things more ardently, and teach others to seek them, saying: Our conversation is in the heavens. Chalcedony. This stone has the colour of a pale lamp: it shines, etc., up to they draw sinners and the frail to themselves and join them to themselves. Emerald. The fourth, of exceeding greenness beyond all grasses and leaves, so much so that even, etc., up to it is called the fourth, faith, on account of the four Gospels.”
