Verse 13. - The breadth of the gate from the roof of one little chamber or lodge to another, measuring from door to door, was five and twenty cubits, which were thus made up: 10 cubits of footway + 12 (2 × 6) cubits for the two guard-rooms + 3 (2 × say 1.5) cubits for the thickness of the two side walls = 25 cubits in all. According to ver. 42, the length of a hewn stone was one cubit and a half. The doors from which the measurements were taken must have been in the side walls at the back of the guard- looms.

40:1-49 The Vision of the Temple. - Here is a vision, beginning at ch. 40, and continued to the end of the book, ch. 48, which is justly looked upon to be one of the most difficult portions in all the book of God. When we despair to be satisfied as to any difficulty we meet with, let us bless God that our salvation does not depend upon it, but that things necessary are plain enough; and let us wait till God shall reveal even this unto us. This chapter describes two outward courts of the temple. Whether the personage here mentioned was the Son of God, or a created angel, is not clear. But Christ is both our Altar and our Sacrifice, to whom we must look with faith in all approaches to God; and he is Salvation in the midst of the earth, Ps 74:12, to be looked unto from all quarters.He measured then the gate from the roof of one little chamber to the roof of another,.... That is, the whole porch, from the extreme part of the roof of one of the little chambers on the north side, to the extreme part of the roof of another of the little chambers on the south; of the roof of these chambers, and the spiritual meaning of it; see Gill on Ezekiel 40:7,

the breadth was five and twenty cubits; reckoning six cubits to one chamber on one side, and six to one chamber on the other side, which make twelve; and a cubit and a half to each back wall of the chambers on the north and south; or two cubits to the spaces before the chambers, and a cubit and a half to each of the caves of the chambers, which either way make fifteen cubits; and ten cubits the breadth of the gate; in all five and twenty cubits; or fourteen yards and three inches:

door against door; not the door of the outward gate against the door of the inward gate; nor the door of one of the little chambers at the east, to the door of another at the west, running lengthways, and so affording a sight quite through the temple; but the door of one of them on the north side over against the door of another on the south, they answering exactly to each other; which still more confirms the similarity and equality of Gospel churches; See Gill on Ezekiel 40:7.
