Revelation 21:16-18

American Standard Version

¹⁶ And 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. ¹⁷ And he measured the wall thereof, a hundred and forty and four cubits, according to the measure of a man, that is, of an angel. ¹⁸ And the building of the wall thereof was jasper: and the city was pure gold, like unto pure glass.
