Revelation 21:14-16

Revised Standard Version Catholic Edition

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

¹⁵ And he who talked to me had a measuring rod of gold to measure the city and its gates and walls. ¹⁶ The city lies foursquare, its length the same as its breadth; and he measured the city with his rod, twelve thousand stadia;^[a] its length and breadth and height are equal.
