Ezekiel 42:4-6

King James Version

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.
