¹⁶ The shape of the city was a square. It was as long as it was wide. The angel measured the city with his stick. It was 12,000 stadia (2,400 kilometres) long. It was as wide and as high as it was long. ¹⁷ He also measured its wall. The size of the wall was 144 cubits (65 metres). That is the way that humans measure things. The angel also measured in the same way.^[a]

¹⁸ The wall was made from the jewel that is called jasper. The city was made from pure gold. The light shone through it, as light shines through clean glass.
