36 And thou shalt make an hanging for the door of the tent, of blue, and purple, and scarlet, and fine twined linen, wrought with needlework.
37 And thou shalt make for the hanging five pillars of shittim wood, and overlay them with gold, and their hooks shall be of gold: and thou shalt cast five sockets of brass for them.
Yesterday we heard of the inner curtain, dividing the interior of the tabernacle into two rooms, now we hear about the outer curtain, which would divide the entire tabernacle from its surrounding courtyard. This door would follow the pattern of the inner curtain and the ceiling, made of fine-twined linen dyed blue, and purple, and scarlet. Thus, all the interior would be uniform.
This curtain would be hung from five pillars, as opposed to the four for the interior curtain. The odd number of pillars suggest that they were spaced evenly across the entrance, and not grouped together on either side with a single wide entryway in the middle. To me that suggests that the interior curtain was similarly broken up by each pillar. This would mean there would be four divisions to pass through the outer curtain, and three divisions to pass through the inner. Alternatively, some depictions assume the external curtain had two pillars grouped on each side, with one support pillar in the middle, creating two divisions, and no support pillar for the interior curtain, creating just one division there.
Another similarity between the exterior and interior curtains is that their pillars would be made of shittim wood overlaid with gold, with golden hooks to hold the curtains. The interior curtains, however, were said to have silver sockets at their base, just like the boards that made up the walls, whereas these external pillars are said to have sockets of brass. It’s a small change, but the use of less-valuable brass suggests that these pillars were to be seen as part of the outer courtyard, rather than part of the tabernacle. We will hear how brass was the chief metal used for the instruments and structures of the courtyard, which seems to correlate to that the place being less sanctified than the tabernacle.
Note: It can be difficult to visualize some of the structures described in these verses. Here is an excellent and extremely focused series of animations that show the visual form of the temple and its instruments, built up verse-by-verse from the Exodus record: https://youtube.com/playlist?list=PLpjohncRg94EZ55nJrbaKfi-lfeo3MFgl&si=6wm1J9Sdnu7LKYC_
