Reference for Eruvin 118:8

may be said to be in agreement even with the view of the Rabbis, since they maintained their view<span class="x" onmousemove="('comment',' That where each courtyard had prepared a separate 'erub the residents of the inner one, despite their right of passage through the outer one, do not restrict the freedom of movement of its residents.');"><sup>19</sup></span> there only where it is a case of two courtyards one behind<span class="x" onmousemove="('comment',' Lit., , 'within'.');"><sup>20</sup></span> the other so that the inner one can well lock its gate and use [its own area only].<span class="x" onmousemove="('comment',' In the interests of the residents of the outer courtyard the inner ones might well be expected to forego their right of passage for that one day.');"><sup>21</sup></span> but can the public domain here be shifted from its place?<span class="x" onmousemove="('comment',' Of course not. As it must remain where it is and there is no gate, fence or any other distinguishing mark to separate the one half of the town from the other, the two halves must be regarded as one unit and, therefore, no separate 'erubs can be permitted.');"><sup>22</sup></span>
