Matthew Poole and continuators on Ezekiel 40:31

31 And the arches thereof were toward the utter court: and palm trees were upon the posts thereof: and the going up to it had eight steps.

In this verse two things are mentioned, wherein this gate differed from the other, first in the Arches or Porch which stood not inward, but outward towards the outer Court, the reason whereof will appear in what follows. The next difference lieth in this, that the Ascent was by eight steps (more then the other, say some, and so make them fifteen) Now, if the Porch to this Gate built outward stood upon such ascent, 'twould be necessary the Pillars should be such as v. 30. expresseth them, 5 Cubits in the breadth of the Basis, and 25 Cubits high.
