Ezekiel 42:3-5

King James Version

³ Over against the twenty cubits which were for the inner court, and over against the pavement which was for the utter court, was gallery against gallery in three stories.

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.
