Ezekiel 42:10-12

10In the thickness of the wall of the court, on the south also, opposite the yard and opposite the building, there were chambers

11with a passage in front of them. They were similar to the chambers on the north, of the same length and breadth, with the same exits and arrangements and doors,

12as were the entrances of the chambers on the south. There was an entrance at the beginning of the passage, the passage before the corresponding wall on the east as one enters them.
