44
From the outside to the inner gate were chambers for the singers in the inner court, [one of] which was at the side of the north gate, with its front toward the south, and one at the side of the south gate facing toward the north.
45
He said to me, "This is the chamber which faces toward the south, [intended] for the priests who keep charge of the temple;
46
but the chamber which faces toward the north is for the priests who keep charge of the altar. These are the sons of Zadok, who from the sons of Levi come near to the LORD to minister to Him."

Below these chambers [was] the entrance on the east side, as one enters them from the outer court.

Then He brought me by way of the north gate to the front of the house; and I looked, and behold, the glory of the LORD filled the house of the LORD, and I fell on my face.
