Revelation 21:19 Meaning

17And he measured the wall thereof, an hundred and forty and four cubits, according to the measure of a man, that is, of the angel.

18And the building of the wall of it was of jasper: and the city was pure gold, like unto clear glass.

19And 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;

20The 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.

21And 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.
