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

Then the man led me north out into the outer courtyard and to the rooms across from the private area and the building.

There was thirty-five feet of the inner courtyard between them and the Temple. On the other side, they faced the stone pavement of the outer courtyard. The rooms were built in three stories like steps and had balconies.

There was a wall outside parallel to the rooms and to the outer courtyard. It ran in front of the rooms for eighty-seven and one-half feet. The row of rooms along the outer courtyard was eighty-seven and one-half feet long, and the rooms that faced the Temple were about one hundred seventy-five feet long. The lower rooms had an entrance on the east side so a person could enter them from the outer courtyard

The priests who enter the Holy Place must leave their serving clothes there before they go into the outer courtyard, because these clothes are holy. After they put on other clothes, they may go to the part of the Temple area which is for the people.”
