Matthew Poole and continuators on Ezekiel 40:48

48 And he brought me to the porch of the house and measured each post of the porch, five cubits on this side, and five cubits on that side : and the breadth of the gate was three cubits on this side, and three cubits on that side.

From the measuring the Building, and Court.

That Porch which joined to the Temple, and was part of the house.

The Post, or Wall on each side of the Gate.

The thickness, or space between the out-side of the Wall, and the in-side of the Wall was five Cubits on each side North and South, if we suppose the breadth of the Porch from North to South, and the length from East to West.

The whole breadth was eleven Cubits, but the breadth of each leaf of this folding gate was three Cubits, and they met, or shut on an upright Post, set in the middle of the Gate space, and this one Cubit broad. And then each leaf hang'd on Posts two cubits thick, which amount to eleven Cubits.
