Ezekiel 40:45

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 ) .
