Ezekiel 41:9-12

9The outer wall of the side rooms was five cubits thick, and the open area between the side rooms of the temple 10and the outer chambers was twenty cubits wide all around the temple. 11The side rooms opened into this area, with one entrance on the north and another on the south. The open area was five cubits wide all around.

12Now the building that faced the temple courtyard on the west was seventy cubits wide,1 and the wall of the building was five cubits thick all around, with a length of ninety cubits.2
