Revelation 11:1; Revelation 21:15-16
And there was given me a reed like unto a rod: and the angel stood , saying , Rise , and measure the temple of God, and the altar, and them that worship therein .
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.
