Ezekiel 8:7-8

The Lord then brought Ezekiel, in his vision, to some entrance to the temple courtyard. There Ezekiel saw a hole in the wall. At the Lord’s command, Ezekiel dug in the wall and discovered an entrance.

There are no other references to a solid wall between the outer and inner courtyards of Solomon’s temple much less to a room or rooms within that wall. Visionary experiences frequently did not correspond to reality in every particular, and this may be one example of this phenomenon. Perhaps what Ezekiel saw was a wall of the temple proper.
