Come and hear: if the tenants of a courtyard and the tenants on its gallery forgot to join together In an erub, any level that is higher than ten handbreadths belongs to the gallery, and any lower level belongs also to the courtyard. This applies only where both the former as well as the latter were occupied by many tenants and each group prepared an ‘erub for itself, or where they belonged to individuals who need not prepare an ‘erub; but if they were occupied by many tenants who forgot to prepare an erub, roof, courtyard, exedra and gallery constitute together a single domain. The reason then is that no ‘erub had been prepared, but if an ‘erub had been prepared this would not have been permitted, would it? — This represents the view of the Rabbis. A deduction from the form of the expression also supports this view, since karpaf and alley were not mentioned. This is conclusive. Come and hear: If five courtyards were open one into the other and also into an alley and all their tenants forgot to prepare an erub, it is forbidden to carry in or to carry out from a courtyard into the alley or from the alley into a courtyard; objects, however, that were in a courtyard when the Sabbath began may be moved about within the courtyard, but in the alley this is forbidden; but R. Simeon permits this for he used to say: Whenever they belong to many people who forgot to prepare an erub, a roof a courtyard, all exedra, a gallery, a karpaf and an alley are jointly regarded as a single domain. The reason then is that no ‘erub had been prepared but if they had prepared One this would not have been the case, would it? — The meaning of ‘no erub had been prepared’ is that the tenants of the courtyards did not prepare an ‘erub jointly, but the courtyard with its houses were joined by an ‘erub. But was it not stated: ‘No ‘erub had been prepared’? — The meaning of an ‘erub had been prepared’ is that there was no shittuf. And if you prefer I might say: R. Simeon was speaking to the Rabbis in accordance with their view. ‘According to my view’, he said, in effect, ‘there is no difference between a case where an erub had been prepared and one where it had not been prepared; but according to your view, would you not agree with me that at least where no ‘erub had been prepared all should be regarded as a single domain?’ And the Rabbis replied: No, they must be regarded as two domains. The Master said: ‘But in an alley this is forbidden’. May it be suggested that this provides support to a ruling R. Zera cited in the name of Rab, for R. Zera citing Rab ruled: In an alley wherein no shittuf had been arranged no objects may be moved about except within four cubits? — Read: ‘But into an alley it is forbidden’. But this is identical, is it not, with the first clause? — The superfluous Mishnah was required: As it might have been presumed that the Rabbis differed from R. Simeon only where an erub had been prepared but that where no ‘erub had been prepared they agreed with him, we were informed [that they differ in both cases]. Said Rabina to R.
