Revelation 21:15-17

New Century Version

¹⁵ The angel who talked with me had a measuring rod made of gold to measure the city, its gates, and its wall. ¹⁶ The city was built in a square, and its length was equal to its width. The angel measured the city with the rod. The city was 1,500 miles long, 1,500 miles wide, and 1,500 miles high. ¹⁷ The angel also measured the wall. It was 216 feet high, by human measurements, which the angel was using.
