출애굽기 27:16의 주석

עמודיהם ארבעה, “the number of their pillars to be four.” In the open space of the entrance to the courtyard in the east, there were only three pillars. However, when speaking of the total number of pillars on the 50 cubits of the eastern side of it there were a total of 11 pillars. When you deduct one pillar each for the north eastern corner or the south eastern corner, whichever you prefer, you are left with ten open spaces for that side, each separated by an open space one cubit wide between each of these pillars. This system continued all the way around the Tabernacle. Eventually, you were left with four empty air spaces and four pillars for the twenty cubits width of the entrance to the courtyard.
