Ezekiel 40:12

There was a barrier before the side rooms , one cubit on either side . And the side rooms were six cubits on either side .

In front of each alcove was a wall one cubit high, and the alcoves were six cubits square.

The space also before the little chambers was one cubit on this side , and the space was one cubit on that side: and the little chambers were six cubits on this side, and six cubits on that side.
