Ezekiel 48:10-12

To these—to the priests—the holy district shall belong: on the north twenty-five thousand cubits in length, on the west ten thousand in width, on the east ten thousand in width, and on the south twenty-five thousand in length. The sanctuary of the LORD shall be in the center. It shall be for the priests of the sons of Zadok, who are sanctified, who have kept My charge, who did not go astray when the children of Israel went astray, as the Levites went astray. And this district of land that is set apart shall be to them a thing most holy by the border of the Levites.
