The Third Beit HaMikdash
In the Second Beis HaMikdash, by contrast, the entire 20 cubits of the Ulam was open across its full length in front of the Sanctuary. Thus, when explaining our Sages’ prohibition against building an exedra that matches the dimensions of the Ulam,3See Avodah Zarah 43a. Tosafos states that the Ulam was open entirely on its eastern side. This conception is reinforced by our Sages’ statement:4Bava Basra 25a. “[Our] world resembles an exedra; its northern side is not enclosed.”5I.e., from this statement, we see that the fourth side of an exedra – and by extension, the Ulam – is open. It is, nevertheless, referred to as, “the opening6I.e., the term petach, “opening,” implies a structure with a gate or door. of the Ulam,” in many places in the Talmud.7See Yoma 67a, 77a, et al. See also sec. 50 below which continues the discussion of the Ulam. This resembles the expression, “the opening to the Sanctuary,” found in the Torah,8Shmos 40:6. and which describes the eastern side of the Sanctuary that was also open entirely. See the explanations in sec. 50 below.
