Matthew Poole and continuators on Ezekiel 42:3

3 Over against the twenty cubits which were for the inner court, and over against the pavement which was for the utter court, was gallery against gallery in three stories .

The twenty cubits space of the Inner Court, or Court of the Temple faced the South front of this row of chambers their Southern lights look'd into this space, and to the North of the Temple.

Which was in the Priests Court, and on the North side of this building, into which pavement the North windows look'd.

That is a Gallery on the South part toward the Inner Court, and a Gallery toward the Pavement North-ward, and between the backs of these Galleries were chambers.

Either in height, or else in three ranks, as now placed, two Galleries on the sides, and a chamber in midst; or two rowes of chambers, and one long Gallery in the middle.
