15. The one who spoke with me had a gold measuring rod to measure the city, its gates, and its wall.
16. The city is laid out in a square; its length and width are the same. He measured the city with the rod at 12,000 stadia. Its length, width, and height are equal.
17. Then he measured its wall, 144 cubits according to human measurement, which the angel used.
18. The building material of its wall was jasper, and the city was pure gold like clear glass.
