Ezekiel 40:44-46

Right where the inside gate complex opened onto the inside courtyard there were two rooms, one at the north gate facing south and the one at the south gate facing north. The man told me, “The room facing south is for the priests who are in charge of the Temple. And the room facing north is for the priests who are in charge of the altar. These priests are the sons of Zadok, the only sons of Levi permitted to come near to GOD to serve him.”
