Revelation 21:15-17

New Living Translation

¹⁵ The angel who talked to me held in his hand a gold measuring stick to measure the city, its gates, and its wall. ¹⁶ When 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.^{[a] 17} Then he measured the walls and found them to be 216 feet thick^[b] (according to the human standard used by the angel).
