The front of the higher stories was not supported on pillars, but there was a narrowing from "the lowest" (chambers) "and" from "the middlemost" (chambers) "from the ground."

For they were in three stories,.... Not only the galleries or posts, but the chambers; they were one over another; there were the lowermost, middlemost, and uppermost; which, as before, may denote the difference in churches, and the different states, conditions, and characters of those that are in them; some being fathers, others young men, and others little children: or their different offices and relations; some being pastors, others deacons, and others private members: or their knowledge of and profession of faith in the doctrine of the Trinity, the mystery of God, and of the Father, and of Christ; and their being baptized in the name of the three divine Persons; and their being built on Christ the foundation, a habitation for God through the Spirit:

but had not pillars as the pillars of the courts; those which supported the porticos and galleries in the courts of the temple, not pillars so thick and strong as they: so the churches represented by these chambers, though they have Gospel ministers, which are as pillars, and valuable members, which are as such, that shall not go out; yet they have not those external supports from great and rich men, but consist generally of the poor of this world, as churches on a civil establishment have, who are supported by the state:

therefore the building was straitened more than the lowest and the middlemost from the ground; the upper part of it, or the uppermost chambers, were more straitened, and had less room in them, than the middlemost, and the middlemost than the lowest; suggesting, that the more heavenly and spiritual men are, the farther they depart from the men of the world and their conversation, from the sentiments and practices of natural men, the more they are exposed to their scorn and contempt, and are the more afflicted and straitened by them.

For they were in three stories, but had not pillars as the pillars of the courts: therefore the building was straitened more than the lowest and the middlemost from the ground.

42:6 As the pillars - So thick and strong as those were.

42:1-20 In this chapter are described the priests' chambers, their use, and the dimensions of the holy mount on which the temple stood. These chambers were many. Jesus said, In my Father's house are many mansions: in his house on earth there are many; multitudes, by faith, are lodging in his sanctuary, and yet there is room. These chambers, though private, were near the temple. Our religious services in our chambers, must prepare for public devotions, and further us in improving them, as our opportunities are.
