Ezekiel 48:16

(16) The measures.—The city itself is to be an exact square of 4,500 reeds, and according to Ezekiel 48:17, was to have “suburbs,” or rather an open space on all sides of 250 reeds. The whole was, therefore, 5,000 reeds—a little less than ten miles—square, the exact width of the space that was left of the oblation, and leaving 10,000 reeds on each side of it.
