Ezekiel 42:6

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

⁵  Now the upper chambers were shorter: for the galleries were higher than these, than the lower, and than the middlemost of the building.

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

⁷  And the wall that was without over against the chambers, toward the utter court on the forepart of the chambers, the length thereof was fifty cubits.

⁸  For the length of the chambers that were in the utter court was fifty cubits: and, lo, before the temple were an hundred cubits.
