Revelation 21:16-18

New King James Version

¹⁶ The city is laid out as a square; its length is as great as its breadth. And he measured the city with the reed: twelve thousand ^[a]furlongs. Its length, breadth, and height are equal. ¹⁷ Then he measured its wall: one hundred and forty-four cubits, according to the measure of a man, that is, of an angel. ¹⁸ The construction of its wall was of jasper; and the city was pure gold, like clear glass.
