Ezekiel 48:10-11

10And for these, even for the priests, shall be the holy oblation; toward the north five and twenty thousand in length, and toward the west ten thousand in breadth, and toward the east ten thousand in breadth, and toward the south five and twenty thousand in length: and the sanctuary of Jehovah shall be in the midst thereof. 11It shall be for the priests that are sanctified of the sons of Zadok, that have kept my charge, that went not astray when the children of Israel went astray, as the Levites went astray.
