John Gill Commentary Ezekiel 40:45

"And he said unto me, This chamber, whose prospect is toward the south, is for the priests, the keepers of the charge of the house;" — Ezekiel 40:45 (ASV)

And he said unto me
The illustrious Person that appeared in a human form, measuring the several parts of the temple, said to the prophet, as follows:

this chamber, whose prospect is toward the south ;
the row of chambers that were on the side of the north gate, facing the south:

is for the priests, the keepers of the charge of the house ;
that observe the keeping of it; observe all the laws and ordinances of God's house, and are careful that the worship of God may be maintained and preserved, to his glory, and their mutual edification:

and which is, or should be, the concern, not of ministers only, but of all true believers, who are priests unto God; that present their bodies and souls before him, as a holy, living, and acceptable sacrifice, which is their reasonable service; and offer up the spiritual sacrifices of prayer and praise to him, through Christ, (Revelation 1:6) (1 Peter 2:5) (Romans 12:1) .
