Charles Ellicott Commentary Ezekiel 45:6

"And ye shall appoint the possession of the city five thousand broad, and five and twenty thousand long, side by side with the oblation of the holy portion: it shall be for the whole house of Israel." — Ezekiel 45:6 (ASV)

The possession of the city.— This portion, more particularly described in Ezekiel 48:15-20, is there called a profane place, though still constituting a part of the oblation. It was the same length and half the width of either of the other portions, and was for the city, and for a common possession of the nation, to supply food for those who serve the city out of all the tribes of Israel (Ezekiel 48:18–19). Nothing is anywhere said to identify this city with Jerusalem, and, indeed, it is described as in a different position geographically (see map). Jerusalem, like the ark, appears to have faded from the prophet’s sight in this vision of the future Church.
