John Wesley on Ezekiel 41:7

An enlarging - Of the side chambers, so much of breadth added to the chamber, as was taken from the thickness of the wall; that is, two cubits in the uppermost, and one cubit in the middle - most, more than in the lowest chambers. A winding about - Winding stairs, which enlarged as the rooms did, and these run up between each two chambers from the bottom to the top; so there were two doors at the head of each pair of stairs, one door opening into one chamber, and the other into the opposite chamber. For the winding about - These stairs, as they rose in height, enlarged themselves too. Round about - On all sides of the house where these chambers were. The breadth - Of each chamber. Increased - Grew broader by one cubit in every upper chamber. From five in the lowest to six in the middle, and to seven in the highest chamber.
