Synopsis of the Books of the Bible, by John Nelson Darby, [1857-62], at sacred-texts.com
The following commentary covers Chapters 40, 41, 42, and 43.
The remaining part of the prophecy is the establishment of His sanctuary in the midst of His people. The reader will perceive that we find in these last chapters a revelation of the same kind as that given to Moses for the tabernacle, and to David for the temple-only that in this case the details are preserved in the writings given to the people by inspiration, as a testimony for the time to come, and to conscience in all times. God takes an interest in His people. He will reestablish His sanctuary among men. Meantime the testimony of this has been given to the people to bring them under the responsibility which this good-will of God towards them involved. For the prophet was commanded to tell the house of Israel all that he had seen; and he did so. When the dimensions of the different parts of the house have been given, the glory of Jehovah fills the house, in the vision, as happened historically at the dedication of the tabernacle and of the temple. Eze 43:7 proclaims that the house, which is the throne and the footstool of Jehovah, should no more be defiled by profane things. The prophet was then to declare that, if Israel renounced their unfaithfulness, Jehovah would return to dwell there. Thus the people are placed at all times under this responsibility. The prophet was to shew the house to Israel that they might repent; and, if they repented, he was to explain it to them in detail. And it is this which takes place at the end. The ordinances of the house were to be shewn them, if they humbled themselves; and in view of this the prophet announces all that was to be done for the cleansing and the consecration of the altar, in order that the regular service might be performed.
