Ezekiel 42:7-12

7As for the 1outer wall by the side of the chambers, toward the outer courtyard facing the chambers, its length was fifty cubits. 8For the length of the chambers which were in the outer courtyard was fifty cubits; and behold, the length of those facing the main room was a 2hundred cubits. 9And below these chambers was the 3entrance on the east side, as one enters them from the outer courtyard.

10In the 4thickness of the 5wall of the courtyard toward the east, facing the 6separate area and facing the building, there were 7chambers. 11And the 8way in front of them was like the appearance of the chambers which were on the north; according to their length, so was their width, and all their exits were according to their building plans and openings. 12Corresponding to the openings of the chambers which were toward the south was an opening at the head of the way, the way in front of the 9wall toward the east, as one enters them.
