Revelation 21:14-16

21st Century King James Version

¹⁴ And the wall of the city had twelve foundations, and on them the names of the twelve apostles of the Lamb.

¹⁵ And he that talked with me had a golden reed to measure the city, and the gates thereof and the walls thereof.

¹⁶ And the city lieth foursquare, and the length 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 of it are equal.
