Ezekiel 48:10-11

10The holy allotment shall be for these, namely for the 1priests, toward the north 25,000 cubits in length, toward the west 10,000 in width, toward the east 10,000 in width, and toward the south 25,000 in length; and the sanctuary of the Lord shall be in its midst.

11It shall be for the priests who are sanctified of the 2sons of Zadok, who have kept My charge, who did not go astray when the sons of Israel went astray as the 3Levites went astray.
