Revelation 21:14-16

New Century Version

¹⁴ The walls of the city were built on twelve foundation stones, and on the stones were written the names of the twelve apostles of the Lamb.

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.
