Revelation 21:16

The city lies foursquare, with its width the same as its length. And he measured the city with the rod, and all its dimensions were equal—12,000 stadia in length and width and height.

Note 12,000 stadia is approximately 1,380 miles or 2,220 kilometers.

And the city lieth foursquare, and the length is as large as the breadth: and he measured the city with the reed, twelve thousand furlongs. The length and the breadth and the height of it are equal.

The city is square. Its length is as great as its width. He measured the city with the reed: twelve thousand twelve stadia. Its length, width, and height are equal.

Note 12,012 stadia = 2,221 kilometers or 1,380 miles. TR reads 12,000 stadia instead of 12,012 stadia.

And the city lieth foursquare, and the length thereof is as great as the breadth: and he measured the city with the reed, twelve thousand furlongs: the length and the breadth and the height thereof are equal.
