Ezekiel 48:10-12

This will be the sacred portion for the priests. It will be 25,000 cubits long on the north side, 10,000 cubits wide on the west side, 10,000 cubits wide on the east side and 25,000 cubits long on the south side. In the center of it will be the sanctuary of the LORD. This will be for the consecrated priests, the Zadokites, who were faithful in serving me and did not go astray as the Levites did when the Israelites went astray. It will be a special gift to them from the sacred portion of the land, a most holy portion, bordering the territory of the Levites.
