Charles Ellicott Commentary Ezekiel 42:3

"Over against the twenty [cubits] which belonged to the inner court, and over against the pavement which belonged to the outer court, was gallery against gallery in the third story." — Ezekiel 42:3 (ASV)

Opposite the twenty.— See under Ezekiel 42:1. This was the space of twenty cubits (I, Ezekiel 40:44–49) to the west of the western Temple chambers.

The pavement.— There is only one pavement mentioned in the outer court, which ran along the inside of the wall. The chamber in question was opposite to the pavement on the north side, as it was opposite to the separate place, etc., on the south— i.e., its length was parallel to both, or east and west. “Utter” again means outer.

Gallery against gallery.— The expression is a difficult one in the original. “Against” is literally, unto the face of, or in front of, and stories is completely missing. The meaning seems to be that in each chamber building, on the north and on the south, there was a gallery in the third storey, so placed on the south side of the north building and the north side of the south building that they faced each other.
