Matthew Poole and continuators on Ezekiel 41:12

12 Now the building that was before the separate place , at the end toward the west, was seventy cubits broad: and the wall of the building was five cubits thick round about, and the length thereof ninety cubits.

This is a new building not yet mention'd, but now measured by it self.

Or over-against.

Either the Temple with all the appendant Treasury Chambers, or the Oracle, which was in the West end of the Temple, and separate from the rest of the Temple. Or that 20 Cubit space, which was cut off from the Chambers, and the five cubits space before them by a breast Wall, as some think.

Of either Temple, Oracle, or foresaid space, toward the West.

As men are not agreed about the Fabrick, and its dimensions here intended to be measured, so they are as little agreed how to compute the Measures, every one however makes out his account, whether the thing he measures be the right or mistaken. First, suppose the Temple and the West part of it from North to South, thus; 20 Cubits the Oracle, each side wall 6 cubits, breadth of Chambers on each side 4, the thickness of the out Walls of these chambers on both sides 5 Cubits each, a void space of 5 cubits compassing the whole, and then the low, or breast Wall that enclos'd this space 5 Cubits thick on each side making up the third 10, produce the 70 Cubits. But they that think of a distinct building on the West-end of the Temple, do also in their method make out the account.

This seems to countenance their opinion, who conceive a distinct building meant.

These proportions are easily laid together, which will make up the total, and agree with the Temple thus; Temple and Oracle with their Walls 70 cubits, Porch eleven, and Chambers, and Walls nine Cubits. And who will have such a new structure here measur'd (which is more than was in the first Temple Fabrick) will make all correspond to their hypothesis, and you may more easily object against anothers, then demonstrate your own guesse. The best is, the errour is not great if a man do erre here.
