Ezekiel 41:2

The door; or the aperture, the open space which let in light, as well as men; properly the door of the porch. Ten cubits, between post and post, on which the folding doors did hang. The sides of the door; the space from the edge of the wall by the posts to the side wall inward was on each side five cubits, on the north side so many, and on the south so many, which make the contents between wall and wall, as the verse hath it, twenty cubits in breadth. The length of the sanctuary, from the porch to the partition between the holy of holies, and the inward front of the wall of the sanctuary, was forty cubits, unless we must take in the thickness of the walls of both sanctuary and holy of holies, of which more may possibly be spoken.
