Revelation 21:19 Revelation 21:19-21 And the foundations of the wall of the city were garnished with all manner of precious stones. The first foundation was jasper; the second, sapphire; the third, a chalcedony; the fourth, an emerald; 20 The fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, a topaz; the tenth, a chrysoprasus; the eleventh, a jacinth; the twelfth, an amethyst. 21 And the twelve gates were twelve pearls; every several gate was of one pearl: and the street of the city was pure gold, as it were transparent glass. In these three verses, the glorious spiritual state of the holy city, the heavenly Jerusalem, the Church of God on earth in the latter days, is mystically figured forth. And the city was pure gold, like the seven churches in Asia in their first constitution \ but in far greater purity, holiness, and glory. The precious stones are, first, a jasper; which is called by jewellers the mother pearl, most precious, clear as crystal; Christ himself is resembled by it, \ like a jasper. Secondly, a sapphire; a precious stone shining with golden sparks, highly prized by the citizens of Tyre, and worn for ornament. \ God promised to lay the foundation of the church with sapphires. \ Read Job 28:14-16; Ezekiel 1:26; Ezekiel 10:1. Thirdly, a chalcedony; fourthly, an emerald, etc. Read Exodus 28:17-21. By these precious stones we are to understand those living stones, which shall be built up a spiritual house, upon that living stone Christ Jesus. \
