Ezekiel 48:10-11

10The holy allotment will be apportioned for these—for the kohanim. Toward the north it will be 25,000 cubits and toward the west 10,000 in width, toward the east 10,000 in width and toward the south 25,000 in length. Adonai’s Sanctuary will be in the midst of it.

11The sanctified portion will be for the kohanim of the sons of Zadok, who kept My charge and did not go astray as the Levites went astray when Bnei-Yisrael went astray.
