15. The one who spoke with me had a gold measuring rod to measure the city, and its gates and its wall.
16. The city is laid out as a square, and its length is as great as the width; and he measured the city with the rod, fifteen hundred miles; its length and width and height are equal.
17. And he measured its wall, seventy-two yards, according to human measurements, which are also angelic measurements.
18. The material of the wall was jasper; and the city was pure gold, like clear glass.
