14 And the wall of the city had twelve foundations, and on them twelve names of the twelve apostles of the Lamb.
15 And he that spoke with me had a golden reed as a measure, that he might measure the city, and its gates, and its wall.
16 And the city lies four-square, and its length is as much as the breadth. And he measured the city with the reed--twelve thousand stadia: the length and the breadth and height of it are equal.
17 And he measured its wall, a hundred and forty-four cubits, a man's measure, that is, the angel's.
18 And the building of its wall was jasper; and the city pure gold, like pure glass:
19 the foundations of the wall of the city were adorned with every precious stone: the first foundation, jasper; the second, sapphire; the third, chalcedony; the fourth, emerald;
20 the fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, topaz; the tenth, chrysoprasus; the eleventh, jacinth; the twelfth, amethyst.
