And the city lies foursquare, and its length is as great as its breadth. And he measured the city with the reed, twelve thousand furlongs; its length and breadth and height are equal.

Revelation 21:15-

7. What is remarkable about the city’s measurements?

⁷ What a remarkable city this is! A perfect cube 12,000 furlongs (about 1,380 miles) [2,220 km]) in perimeter, surrounded by a wall 144 cubits, or 210 feet [64 m], in height. No literal city could ever have such measurements. It would cover a territory about 14 times as large as modern Israel, and it would tower almost 350 miles [560 km] into outer space! Revelation was given in signs. So, what do these measurements tell us about heavenly New Jerusalem?

The figure 12 that appears in the 12,000-furlong measurement of the city​—with the length, breadth, and height being equal—​is used figuratively in organizational settings in Bible prophecy. Hence, New Jerusalem is a superbly designed organizational arrangement for accomplishing God’s eternal purpose. New Jerusalem, together with the King Jesus Christ, is Jehovah’s Kingdom organization. Then there is the shape of the city: a perfect cube. In Solomon’s temple, the Most Holy, containing a symbolic representation of Jehovah’s presence, was a perfect cube. (1 Kings 6:19, 20) How fitting, then, that New Jerusalem, illuminated by the glory of Jehovah himself, is seen as a perfect, large-scale cube! All its measurements are perfectly balanced. It is a city without irregularities or defects.​—Revelation 21:22.
