Ezekiel 48:10-11

10And for them, for the priests, shall be the holy heave-offering, toward the north five and twenty thousand, and toward the west the breadth ten thousand, and toward the east the breadth ten thousand, and toward the south the length five and twenty thousand: and the sanctuary of Jehovah shall be in the midst of it.

11[It shall be] for the priests that are hallowed of the sons of Zadok, who kept my charge and went not astray when the children of Israel went astray, as the Levites went astray.
