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

Then the man led me out of the Temple courtyard by way of the north gateway. We entered the outer courtyard and came to a group of rooms against the north wall of the inner courtyard.

One block of rooms overlooked the 35-foot width of the inner courtyard. Another block of rooms looked out onto the pavement of the outer courtyard. The two blocks were built three levels high and stood across from each other.

There was an outer wall that separated the rooms from the outer courtyard; it was 87-1/2 feet long. This wall added length to the outer block of rooms, which extended for only 87-1/2 feet, while the inner block—the rooms toward the Temple—extended for 175 feet. There was an eastern entrance from the outer courtyard to these rooms.

When the priests leave the sanctuary, they must not go directly to the outer courtyard. They must first take off the clothes they wore while ministering, because these clothes are holy. They must put on other clothes before entering the parts of the building complex open to the public.”
