Ezekiel 42:10-12

10Also there were chambers in the thickness of the wall of the court toward the east, opposite the separating courtyard and opposite the building.

11There was a walk in front of them also, and their appearance was like the chambers which were toward the north; they were as long and as wide as the others, and all their exits and entrances were according to plan.

12And corresponding to the doors of the chambers that were facing south, as one enters them, there was a door in front of the walk, the way directly in front of the wall toward the east.
