Ezekiel 42:2-4

King James Version

² Before the length of an hundred cubits was the north door, and the breadth was fifty cubits.

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.
