The Third Beit HaMikdash
The width of the Sanctuary from north to south was 20 cubits.17Yechezkel 41:2. In the center of its eastern wall, there was an entrance that was 10 cubits wide. This is derived from the verse, “On the flanks of the entrance, there were 5 cubits on one side and 5 cubits on the other.” “Its doorpost was rectangular.”18Ibid.:21.
The Third Beit HaMikdash
“He measured its length,”1Yechezkel 41:2. i.e., the length of the Sanctuary from east to west, “as 40 cubits.”
