Revelation 21:14-20

14The city's wall has a foundation of 12 strong stones. The names of the Lamb's 12 apostles were written on those 12 stones.

15The angel who talked to me had a long gold stick. He used it to measure things. So he could measure the city and its gates and its walls.

16The 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.

17He 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.

18The 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.

19The strong stones that were the foundation of the city's wall were very beautiful. They had valuable jewels in them that were different colours. Each great stone had its own special jewel. They were called: 1. Jasper; 2. Sapphire; 3. Agate; 4. Emerald;

205. Onyx; 6. Carnelian; 7. Quartz; 8. Beryl; 9. Topaz; 10. Chrysoprase; 11. Jacinth; 12. Amethyst.
