Revelation 21:14-17
English Standard Version
15And the one who spoke with me had a measuring rod of gold to measure the city and its gates and walls.
16The city lies foursquare, its length the same as its width. And he measured the city with his rod, 12,000 stadia. Its length and width and height are equal.
17He also measured its wall, 144 cubits by human measurement, which is also an angel 's measurement.
