Ezekiel 42:4-7 American Standard Version (ASV)

4. And before the chambers was a walk of ten cubits’ breadth inward, a way of one cubit; and their doors were toward the north.

5. Now the upper chambers were shorter; for the galleries took away from these, more than from the lower and the middlemost, in the building.

6. For they were in three stories, and they had not pillars as the pillars of the courts: therefore the uppermost was straitened more than the lowest and the middlemost from the ground.

7. And the wall that was without by the side of the chambers, toward the outer court before the chambers, the length thereof was fifty cubits.
