Revelation 21:14-20

14And the wall of the city had twelve foundations, and on them twelve names of the twelve apostles of the Lamb. 15And he that spake with me had for a measure a golden reed to measure the city, and the gates thereof, and the wall thereof. 16And the city lieth foursquare, and the length thereof is as great as the breadth: and he measured the city with the reed, twelve thousand furlongs: the length and the breadth and the height thereof are equal. 17And he measured the wall thereof, a hundred and forty and four cubits, according to the measure of a man, that is, of an angel. 18And the building of the wall thereof was jasper: and the city was pure gold, like unto pure glass. 19The 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, chalcedony; the fourth, emerald; 20the fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, topaz; the tenth, chrysoprase; the eleventh, jacinth; the twelfth, amethyst.
