Ezekiel 41:9-12

9The thickness of the wall, which was for the side-chambers, on the outside, was five cubits: and that which was left was the place of the side-chambers that belonged to the house. 10And between the chambers was a breadth of twenty cubits round about the house on every side. 11And the doors of the side-chambers were toward the place that was left, one door toward the north, and another door toward the south: and the breadth of the place that was left was five cubits round about.

12And the building that was before the separate place at the side toward the west was seventy cubits broad; and the wall of the building was five cubits thick round about, and the length thereof ninety cubits.
