Ezekiel 40:46
and the chamber that faces north is for the priests who keep charge of the altar. These are the sons of Zadok, the only Levites who may approach the LORD to minister before Him.”
Berean Standard Bible
And the chamber whose prospect is toward the north is for the priests, the keepers of the charge of the altar: these are the sons of Zadok among the sons of Levi, which come near to the LORD to minister unto him.
The room which faces toward the north is for the priests who perform the duty of the altar. These are the sons of Zadok, who from among the sons of Levi come near to the LORD to minister to him.”
