Ezekiel 48:9-12

9The portion that you shall set apart for the Lord shall be 25,000 cubits in length, and 20,000 in breadth.

10These shall be the allotments of the holy portion: the priests shall have an allotment measuring 25,000 cubits on the northern side, 10,000 cubits in breadth on the western side, 10,000 in breadth on the eastern side, and 25,000 in length on the southern side, with the sanctuary of the Lord in the midst of it.

11This shall be for the consecrated priests, the sons of Zadok, who kept my charge, who did not go astray when the people of Israel went astray, as the Levites did.

12And it shall belong to them as a special portion from the holy portion of the land, a most holy place, adjoining the territory of the Levites.
