The foundations of the side chambers - Therefore the height of the side-chambers from the floor was six cubits there being three stories, which corresponds sufficiently with the twenty cubits which was the height of the temple. "A great cubit" is probably an architectural term to denote the line of junction between two stories, which would be that of the ceiling of the lower and the floor of the upper story.

I saw also the height of the house round about,.... Not of the temple itself, but of the chambers, and the three stories of them, which went round about it; and particularly the height of the highest storey, which yet is not given: it could not be so high as the temple itself; for then there would have been no room for windows to let in light into it:

the foundations of the side chambers were a full reed of six great cubits; not of the lowest storey of them, for that was but four cubits broad, Ezekiel 41:5, nor of the middlemost, which was five; but of the uppermost, which was six; and these were cubits of the largest size, a hand's breadth larger than the common cubit, and made one full reed, or three yards and a half; see Ezekiel 40:5, these foundations signify the same as the twelve foundations of the wall of the New Jerusalem; and which are no other than the one foundation Christ, ministerially laid by his twelve apostles; and who is the only foundation of his church and people, and is a sure one, Revelation 21:14.

I saw also the height of the house round about: the foundations of the side chambers were a full reed of six great cubits.

41:8 The foundations - The lowest chamber had properly a foundation laid on the earth, but the floor of the middle, and highest story must be accounted here a foundation; so from the ground to the ceiling of the first room, was six great cubits; from the first to the second, six great cubits; and from the third floor to the roof of the chamber, a like number; to which add we one cubit for thickness of each of the three floors, you have twenty - one cubits for height, ten yards and a half high.

great-literally, "to the extremity" or root, namely, of the hand [Henderson]. "To the joining," or point, where the foundation of one chamber ceased and another began [Fairbairn].

41:1-26 After the prophet had observed the courts, he was brought to the temple. If we attend to instructions in the plainer parts of religion, and profit by them, we shall be led further into an acquaintance with the mysteries of the kingdom of heaven.
