Ezekiel 42:10-14

In the thickness of the wall of the courtyard toward the east, facing the separate area and facing the building, there were chambers.

And the way in front of them was like the appearance of the chambers which were on the north; according to their length, so was their width, and all their exits were according to their building plans and openings.

Corresponding to the openings of the chambers which were toward the south was an opening at the head of the way, the way in front of the wall toward the east, as one enters them.

Then he said to me, “The north chambers and the south chambers, which are opposite the separate area, they are the holy chambers where the priests who are near to the Lord shall eat the most holy things. There they shall set the most holy things, the grain offering, the sin offering, and the guilt offering; for the place is holy.

When the priests enter, they shall not go out into the outer courtyard from the sanctuary without laying their garments there in which they minister, for they are holy. They shall put on other garments; then they shall approach that which is for the people.”
