Charles Ellicott Commentary Ezekiel 41:4

"And he measured the length thereof, twenty cubits, and the breadth, twenty cubits, before the temple: and he said unto me, This is the most holy place." — Ezekiel 41:4 (ASV)

Before the temple— Temple is here, as in Ezekiel 41:1, used of the Holy Place, and before, or west of this, was the Holy of Holies, an exact cube, of the same size as in Solomon’s Temple. The thickness of the dividing wall between the Holy Place and the Holy of Holies is nowhere mentioned, nor is it taken into account in the measurements. It was merely a division, either a veil, or perhaps a screen of wood, and occupied little room.
