Revelation 21:11-18

11It shone with the glory of God and sparkled like a precious stone—like jasper as clear as crystal.

12The city wall was broad and high, with twelve gates guarded by twelve angels. And the names of the twelve tribes of Israel were written on the gates.

13There were three gates on each side—east, north, south, and west.

14The wall of the city had twelve foundation stones, and on them were written the names of the twelve apostles of the Lamb.

15The angel who talked to me held in his hand a gold measuring stick to measure the city, its gates, and its wall.

16When he measured it, he found it was a square, as wide as it was long. In fact, its length and width and height were each 1,400 miles.

17Then he measured the walls and found them to be 216 feet thick (according to the human standard used by the angel).

18The wall was made of jasper, and the city was pure gold, as clear as glass.
