Ezekiel 42:1, 3, 7, 8, 9, 14

Then the man led me northward into the outer court and brought me to the rooms opposite the temple courtyard and opposite the outer wall on the north side.

Both in the section twenty cubits from the inner court and in the section opposite the pavement of the outer court, gallery faced gallery at the three levels.

There was an outer wall parallel to the rooms and the outer court; it extended in front of the rooms for fifty cubits.

While the row of rooms on the side next to the outer court was fifty cubits long, the row on the side nearest the sanctuary was a hundred cubits long.

The lower rooms had an entrance on the east side as one enters them from the outer court.

Once the priests enter the holy precincts, they are not to go into the outer court until they leave behind the garments in which they minister, for these are holy. They are to put on other clothes before they go near the places that are for the people.”
