Ezekiel 40:44-46 - Rooms For Priests And Other Worship Leaders
44 On the outside of the innermore door were the singers' chambers in the inward court beside the North door over against the South. There stood one also, beside the east door northward. 45 And he said unto me, "This chamber on the South side belongeth to the priests, that keep the habitation: 46 and this toward the North, is the priests' that wait upon the altar: these are the sons of Zadok, which of the sons of Levi come near to the LORD, to minister unto him."
