Matthew Poole and continuators on Ezekiel 41:3

3 Then went he inward , and measured the post of the door , two cubits: and the door, six cubits; and the breadth of the door, seven cubits.

From the Porch thro' the body of the Temple, to the Partition between the body of the Temple and the holy of holies, or the Oracle,

Either the thickness of that Partition Wall, or of the Pylasters, which stood one on one side, and the other on the other side of the door

Or entrance out of the Temple into the Oracle.

This door was six cubits high, say some, but, more likely, 'twas six cubits broad, and an upright Bar or Post on which the leafes did meet, and which was of one Cubits breadth, make out the seven Cubits mention'd in the last words of this verse.
