Ezekiel 41:9

9 The breadth of the wall that [is] to the side-chamber at the outside [is] five cubits; and that which is left [is] the place of the side-chambers that [are] to the house.

Ezekiel 41:9 Meaning and Commentary

Ezekiel 41:9

The thickness of the wall, which was for the side chambers
without, was five cubits
This is the outward wall of the chambers, north and south, which was five cubits thick, made of stone; (See Gill on Ezekiel 41:5), and that which was left was the place of the side chambers that were
within;
this was a void space, not built upon, which was before the chambers that stood within it; and was a space to walk in for those that dwelt in the chambers, or to go in from chamber to chamber; which also was five cubits in breadth, as appears from the next verse. This may denote the communion of churches, and the members of them one with another.

Ezekiel 41:9 In-Context

7 And a broad place and a turning place still upwards [are] to the side-chambers, for the turning round of the house [is] still upwards all round about the house: therefore the breadth of the house [is] upwards, and so the lower one goeth up unto the higher by the midst.
8 And I have looked at the house, the height all round about: the foundations of the side-chambers [are] the fulness of the reed, six cubits by the joining.
9 The breadth of the wall that [is] to the side-chamber at the outside [is] five cubits; and that which is left [is] the place of the side-chambers that [are] to the house.
10 And between the chambers [is] a breadth of twenty cubits round about the house, all round about.
11 And the opening of the side-chamber [is] to the place left, one opening northward, and one opening southward, and the breadth of the place that is left [is] five cubits all round about.
