Revelation 21:15
King James Version
And he that talked with me had a golden reed to measure the city, and the gates thereof, and the wall thereof.
Revelation 21:15 in context
On the east three gates; on the north three gates; on the south three gates; and on the west three gates.
And the wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb.
And he that talked with me had a golden reed to measure the city, and the gates thereof, and the wall thereof.
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.
And he measured the wall thereof, an hundred and forty and four cubits, according to the measure of a man, that is, of the angel.
