John Wesley on Ezekiel 40:13

From the roof - From the extremity of one little chamber on the north side of the gate, to the extremity of the opposite chamber on the south side, and so one cubit and half for the back wall of one chamber, and as much for the back wall of the other chamber, with the length of the chambers, six cubits each, and ten for the breadth of the gate, amounts to twenty five cubits. Door against door - It seems the doors of the chambers were two in each chamber in the east and west parts, and so exactly set, that the doors being all open you had a clear prospect through all the chambers to the temple.
