Ezekiel 41:12 (KJV)

And between the chambers was the wideness of twenty cubits round about the house on every side.

And 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.

Now the building that was before the separate place at the end 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.

So he measured the house, an hundred cubits long; and the separate place, and the building, with the walls thereof, an hundred cubits long;

Also the breadth of the face of the house, and of the separate place toward the east, an hundred cubits.
