Adam Clarke on Ezekiel 48:21

And the residue - for the prince - His portion was alongside that of the Levites, from west to east; these were on each side twenty-five thousand cubits in length, from the east to the west. by twelve thousand five hundred cubits in breadth from north to south. The space both above and below was equal, between the tribe of Judah and that of Benjamin to north and south; and the portion of the Levites, which had Judah and Benjamin to the north and south, and the portion of the prince to the east and to the west. See the map.
