Ezekiel 40:44-46 - Rooms For Priests And Other Worship Leaders
44 And outside the inner gate were the chambers for the singers in the inner court, one at the side of the north gate; facing toward the south: one at the side of the east gate facing toward the north. 45 And he said unto me, This chamber, facing toward the south, is for the priests, the keepers in charge of the house. 46 And the chamber facing toward the north is for the priests, the keepers in charge of the altar: these are the sons of Zadok among the sons of Levi, who come near to the LORD to minister unto him.
