Ezekiel 41:11 and the Temple Vision

Hebrew (Leningrad Codex): וּפֶ֤תַח הַצֵּלָע֙ לַמֻּנָּ֔ח פֶּ֤תַח אֶחָד֙ דֶּ֣רֶךְ הַצָּפֹ֔ון וּפֶ֥תַח אֶחָ֖ד לַדָּרֹ֑ום וְרֹ֙חַב֙ מְקֹ֣ום הַמֻּנָּ֔ח חָמֵ֥שׁ אַמֹּ֖ות סָבִ֥יב ׀ סָבִֽיב׃

Ezekiel's temple vision is one of the most fascinating accounts in the Bible to me--it raises numerous questions and there is so much to learn from the vision. I've often tried to envision just what the prophet saw although our Pure Worship publication supplied some help.

NET: "There were entrances from the side chambers toward the open area, one entrance toward the north, and another entrance toward the south; the width of the open area was 8¾ feet[a] all around."

Ftn: tn Heb “5 cubits” (i.e., 2.625 meters).

The NA Commentary on Ezekiel (Lamar E. Cooper, Sr.) makes these remarks:  "The base extended away from the building for five cubits on every side (v. 11). Behind the temple was another building seventy by ninety cubits with a wall five cubits thick (v. 12). The exact function of this building is unknown (see Figs. 2 and 3),42 although it has been associated with the parbar (“court”) of 1 Chr 26:18, which probably was an open area. This open area may have been in front of the building, or it may refer to the open area of the large room inside the building, whose purpose is unclear."
