Revelation 21:15-17

Living Bible

¹⁵ The angel held in his hand a golden measuring stick to measure the city and its gates and walls. ¹⁶ When he measured it, he found it was a square as wide as it was long; in fact it was in the form of a cube, for its height was exactly the same as its other dimensions—1,500 miles each way. ¹⁷ Then he measured the thickness of the walls and found them to be 216 feet across (the angel called out these measurements to me, using standard units).^[a]
