The position of the "chamber" looking to the north commanded a view of the brasen altar and the sacrifices, which were prepared at the north side of the altar.

The sons of Zadok - The priests were all descended from one or other of the two sons of Aaron, Eleazar and Ithamar. David distributed the priestly offices between the families of Zadok, the representative of Eleazar, and Ahimelech, the representative of Ithamar 1 Chronicles 24:3. From the time of Solomon not only the high priesthood, but the priesthood itself, so far as concerned its service, that of offering upon the two altars, seems to have been confined to the descendants of Zadok (see 1 Chronicles 6:49-53). Perhaps the other offices, such as those mentioned in Ezekiel 40:45, were performed by the descendants of Abiathar and Ithamar. Compare 1 Samuel 2:36, and below, Ezekiel 43:19; Ezekiel 44:15; Ezekiel 48:11. The priests who had charge of the sacrifices were distinguished from the rest of the Levitical priests, "as they which come near to the Lord, and Ezekiel 42:13 the priests that approach unto the Lord."

And the chamber whose prospect is towards the north,.... The row of chambers on the side of the east gate; that side of it that was towards the north, and which the chambers in it faced:

is for the priests, the keepers of the charge of the altar; the ministers of the Gospel, that take care of the altar, of public worship; that preach the Gospel, and administer ordinances; and who are to be taken care of themselves, and live of the Gospel, and have everything provided for them that is necessary, 1 Corinthians 9:13,

these are the sons of Zadok, among the sons of Levi; these Levites, or priests, were of the family of Zadok; who descended from Aaron, and was the eldest house of Aaron, to whom the priesthood belonged; though it had been usurped a long time by the family of Ithamar; but, in Solomon's time, Abiathar, of that family, was dispossessed of it, and Zadok was placed in his stead, whose name signifies "just", or righteous; and was a type of Christ, the holy and just One, whose spiritual children and offspring are here meant:

which come near to the Lord to minister unto him; both preachers and people, who have near access to God through Christ, and minister before him in holy things, in praying, preaching, administering ordinances, and attending on the same.

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.

40:46 The keepers - To preserve the fire perpetually on the altar.

46. Zadok-lineally descended from Aaron. He had the high priesthood conferred on him by Solomon, who had set aside the family of Ithamar because of the part which Abiathar had taken in the rebellion of Adonijah (1Ki 1:7; 2:26, 27).

40:1-49 The Vision of the Temple. - Here is a vision, beginning at ch. 40, and continued to the end of the book, ch. 48, which is justly looked upon to be one of the most difficult portions in all the book of God. When we despair to be satisfied as to any difficulty we meet with, let us bless God that our salvation does not depend upon it, but that things necessary are plain enough; and let us wait till God shall reveal even this unto us. This chapter describes two outward courts of the temple. Whether the personage here mentioned was the Son of God, or a created angel, is not clear. But Christ is both our Altar and our Sacrifice, to whom we must look with faith in all approaches to God; and he is Salvation in the midst of the earth, Ps 74:12, to be looked unto from all quarters.
