King James Version (KJV) - Revelation 21:16 >

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.

Berean Study Bible (BSB) - 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.
