Revelation 21:14-20

14And the wall of the city had twelve foundations, and on them the twelve names of the twelve emissaries of the Lamb.

15The angel speaking with me had a gold measuring rod to measure the city and its gates and walls.

16The city is laid out as a square—its length the same as its width. He measured the city with the rod—12,000 stadia. Its length and width and height are equal.

17He also measured its wall—144 cubits by human measurement, which is also an angel’s measurement.

18The material of the city’s wall was jasper, while the city was pure gold, clear as glass.

19The foundations of the city wall were decorated with every kind of precious stone—the first foundation was jasper; the second, sapphire; the third, chalcedony; the fourth, emerald;

20the fifth, sardonyx; the sixth, carnelian; the seventh, yellow topaz; the eighth; beryl; the ninth, topaz; the tenth, chrysoprase; the eleventh, jacinth; the twelfth, amethyst.
