Ezekiel 40:44-46

44From the outside to the 1inner gate were 23chambers for the 4singers in the inner courtyard, one of which was at the 5side of the north gate, with 6its front toward the south, and one at the 7side of the 8south gate facing north.

45Then he said to me, “This is the 9chamber which faces south, intended for the priests who 10are 11responsible for the 12temple;

46but the 13chamber which faces north is for the priests who 14are 15responsible for the altar. They are the 16sons of Zadok, who from the sons of Levi 17come near to the Lord to serve Him.”
