Ezekiel 41:8-11

8I saw also that the House had a raised platform all around; the foundations of the side chambers were a full rod of six cubits up to the joint.

9The thickness of the outer wall of the side chambers was five cubits. The space between the side chambers of the House

10and the outer chambers was 20 cubits wide all around the House on every side.

11The doors of the side chambers were toward the space, one door toward the north and another door toward the south. The width of the space was five cubits all around.
