Ezekiel Chapter 48 Vs. 16

The Division of the Land

And these shall be the measures thereof; the north side four thousand and five hundred, and the south side four thousand and five hundred, and on the east side four thousand and five hundred, and the west side four thousand and five hundred. Eze. 48:16

the measures thereof;... The city itself, inside the walls, will be 4,500 square reeds (about 9 square miles). This, with the 250-reeds space (2,625 feet) for the suburbs on the north, south, east and west sides will make the walled city and suburbs about 10 miles square (Eze. 48:16-17). The remaining portion on each side of the city, which will be farm land to serve the city, will measure 5,000 by 10,000 reeds, or about 10 by 20 miles for each side (Eze. 48:18-19).

This land, that had been set aside, was a square. Each side was 4500 reeds.
