Ezekiel 48:10-12

The holy allotment shall be for these, namely for the priests, toward the north 25,000 cubits in length, and toward the west 10,000 in width, and toward the east 10,000 in width, and toward the south 25,000 in length; and the sanctuary of the LORD shall be in the midst of it. It shall be for the priests who are sanctified of the sons of Zadok, who have kept My charge, and who did not go astray when the children (descendants) of Israel went astray as the [other] Levites did. And this [land offering] shall be an allotment to them from the allotment of the land, a most holy portion beside the border of the [other] Levites.
