Revelation 21:14-16

The Voice

¹⁴ And the city wall sat perfectly on twelve foundation stones, and on them were inscribed the names of the twelve emissaries^[a] of the Lamb.

¹⁵ My guide held a golden measuring rod. With it he measured the city and the gates and the walls. ¹⁶ And the city is laid out with four corners in a perfect square, the length the same as its width. He measured the city with his measuring rod, and the result was that its length and width and height are equal: 1,444 miles, a perfect cube.
