Revelation 21:15-17

21:15 The angel who spoke to me had a golden measuring rod with which to measure the city and its foundation stones and wall. 21:16 Now the city is laid out as a square, its length and width the same. He measured the city with the measuring rod at fourteen hundred miles (its length and width and height are equal). 21:17 He also measured its wall, one hundred forty-four cubits according to human measurement, which is also the angel’s.
