20 Come and hear what R'Hiyya taught: A wall of which one side recedes more than the other, whether [the recess can be] seen from without and appears even from within or whether it can be seen from within and appears even from without, may be regarded as [being provided with] a side-post!<span class="x" onmousemove="('comment',' Supra 9b, q.v. notes. The recession being presumably accidental, does not the recognition of the validity of the side-post present an objection against Raba? lh,fust oue vh,fust oe');"><sup>46</sup></span> - Here also it is a case where it was originally constructed for the purpose. If so, what need was there to tell us [the obvious]? - It is this that we were informed: [If the recess can be] seen from without though it appears even from within, [the wall] may be regarded as [provided with] a side-post. Come and hear [of the incident] where Rab was sitting in a certain alley and R'Huna sat before him when he said to his attendant, 'Go, bring me a jar of water'. By the time the latter returned, the side-post fell dow and he motioned to him with his hand to remain in his place.<span class="x" onmousemove="('comment',' So according to MS.M. and R. Han. 'remain in your place'. According to cur. edd., 'he remained in his place', render, 'He motioned to him with his hand and (the latter) remained in his place'.');"><sup>47</sup></span> Said R'Huna to him, 'Is not the Master of the opinion that one may rely upon the palm-tree? '<span class="x" onmousemove="('comment',' That grew at the side of the entrance to the alley.');"><sup>48</sup></span> 'This young Rabbi', he replied: 'seems to think that people cannot explain a ruling they have heard! Did we rely upon it since yesterday? '<span class="x" onmousemove="('comment',' They did not. Hence they could not treat the palm-tree as a valid side-post for the alley.');"><sup>49</sup></span> The reason then<span class="x" onmousemove="('comment',' Why the palm-tree could not be regarded as a side-post.');"><sup>50</sup></span> is that no one had relied on it;<span class="x" onmousemove="('comment',' Before the commencement of the Sabbath.');"><sup>51</sup></span> but if they had relied on it,<span class="x" onmousemove="('comment',' Before the commencement of the Sabbath.');"><sup>51</sup></span> it would have been regarded as a valid side-post.<span class="x" onmousemove="('comment',' This then proves that the law is in agreement with Abaye.');"><sup>52</sup></span> Might not one suggest that Abaye and Raba differed only where [the residents] did not rely on it,<span class="x" onmousemove="('comment',' A side-post of accidental origin.');"><sup>53</sup></span> but that where they did rely on it, it is regarded as a valid side-post?<span class="x" onmousemove="('comment',' So that Rab's ruling would be in agreement with the opinion of both Abaye and Raba.');"><sup>54</sup></span> - This cannot be entertained at all; for there was a certain piazza at the house of Bar Habu,<span class="x" onmousemove="('comment',' And one of its supporting poles was situated at the entrance to an alley.');"><sup>55</sup></span> about which Abaye and Raba were always<span class="x" onmousemove="('comment',' Lit., 'all their years'.');"><sup>56</sup></span> in dispute.<span class="x" onmousemove="('comment',' The former regarding it as a valid side-post and the latter denying its validity. From which it follows that the dispute between Abaye and Raba as to the validity of a side-post of accidental origin extends also to one upon which the residents had relied.');"><sup>57</sup></span> <big><b>MISHNAH: </b></big>SIDE-POSTS MAY BE MADE OF ANYTHING, EVEN OF AN ANIMATE OBJECT, BUT R'MEIR<span class="x" onmousemove="('comment',' Separate ed. of the Mishnah read: 'R.
