Ezekiel 42:7-9

7There was a wall that went across the outside yard in front of the lowest rooms. The wall was 25 metres long.

8The row of rooms in the outside yard was also 25 metres long. But the other row of rooms in the inside yard, opposite the temple, was 50 metres long.

9The lowest level of rooms had an entrance from the outside yard at the east end of the building.
