Ezekiel 41:15

-17 ‘And the inner temple and the vestibules of the court, the thresholds, and the narrowing windows, and the galleries round about on their three storeys over against the threshold, were panelled with wood round about, even from the ground up to the windows, (now the windows were covered), to the space above the door, even to the inner house and outside, and all the wall inside and outside, by measure.'

All the interiors of the sanctuary and the rooms connected with it were panelled with wood from the ground upwards, to a level above the doors. This probably means, as with Solomon's temple (1 Kings 6:18), that they were totally covered. No stonework must be observable within the sanctuary. Solomon's temple also had gold overlay (1 Kings 6:22), but there is no gold in the heavenly temple. Gold is of insufficient value and too ornate. God's ways are not man's ways.
