Consequently it must refer to a case where the heathen came home on the Sabbath, and in connection with this it was stated that ‘where they do impose restrictions upon one another but may not join in an ‘erub they may not renounce their rights in favour of one of them’. This is conclusive. I, observed R. Joseph, have never before heard this reported ruling. Said Abaye to him: You yourself have taught it to us and you said it in connection with the following. For Samuel said that ‘no domain may be renounced where two courtyards are involved nor may it be renounced in the case of a ruin’, and you told us in connection with it that when Samuel said that ‘no domain may be renounced where two courtyards are involved’ he meant it to apply only to two courtyards that had one door in common, but where one courtyard was within the other, since the tenants impose restrictions upon one another, they may also renounce their rights. Could I, the former questioned, have reported such a ruling in the name of Samuel? Did not Samuel in fact state: ‘In the laws of ‘erub we can only be guided by the wording of our Mishnah’ , [viz.,] ‘the tenants of one courtyard’, but not those of two courtyards? — When you told us, the other explained, that ‘In the laws of ‘erub we can only be guided by the wording of our Mishnah’ you said It in connection with the following: Since an alley to its courtyards is as a courtyard to its houses. [To turn to] the main text: Samuel ruled that no domain may be renounced where two courtyards are involved nor may it be renounced in the case of a ruin. R. Johanan, however, ruled: A domain may be renounced even where two courtyards are involved and it may also be renounced in the case of a ruin. And both had to be mentioned. For if the two courtyards only had been mentioned it might have been assumed that only in this case did Samuel maintain his view, since the use of one is quite independent of that of the other, but that in the case of a ruin, the use of which is common to the two tenants, he agrees with R. Johanan. And if the latter only had been stated it might have been presumed that in this case only did R. Johanan mention his view, but that in the former case he agrees with Samuel. Hence both were required. Abaye stated: Samuel's ruling that ‘no domain may be renounced where two courtyards are involved’ applies only to two courtyards that had one door in common but where two courtyards were one within the other, since the tenants impose restrictions upon one another, they may also renounce their rights. Raba stated: Even in the case of two courtyards one of which was within the other the tenants may sometimes renounce their rights and sometimes they may not renounce them. How IS this [possible]? If the tenants deposited their ‘erub in the outer courtyard and one tenant, whether of the inner courtyard or of the outer courtyard, forgot to participate in the ‘erub, the use of both courtyards is restricted, If they deposited their ‘erub in the inner courtyard and one tenant of the inner courtyard forgot to participate in the ‘erub, the use of both courtyards is restricted. If, however, a tenant of the outer courtyard forgot to participate in the ‘erub, the use of the inner courtyard is unrestricted while that of the outer one is restricted. ‘If the tenants deposited their ‘erub in the outer courtyard and one tenant, whether of the inner courtyard or of the outer courtyard, forgot to participate in the ‘erub, the use of both courtyards is restricted’. For in whose favour could this tenant of the inner courtyard renounce his right? Should he renounce it in favour of the tenants of the inner courtyard? But their ‘erub, surely, is not with them! Should he renounce his right in favour of the tenants of the outer courtyard also? Surely no domain may be renounced where two courtyards are involved! As to the tenant of the outer courtyard too in whose favour could he renounce his right? Should he renounce it in favour of the tenants of the outer courtyard? There would still remain the tenants of the inner courtyard who would impose the restrictions upon them! Should he renounce it in favour of the tenants of the inner courtyard also? Surely no domain may be renounced where two courtyards are involved! ‘If they deposited their ‘erub in the inner courtyard and one tenant of the inner courtyard forgot to participate in the ‘erub, the use of both courtyards is restricted’. For in whose favour could this tenant of the inner courtyard renounce his right? Should he renounce it in favour of the tenants of the inner courtyard? There would still remain the tenants of the outer courtyard who would impose restrictions upon them! Should he renounce his right in favour of the tenants of the outer courtyard also? Surely no domain may be renounced where two courtyards are involved!53ᵃᵇᶜᵈᵉᶠᵍʰⁱʲᵏˡᵐⁿᵒᵖᵠʳˢᵗᵘᵛʷˣʸᶻᵃᵃᵃᵇᵃᶜᵃᵈᵃᵉᵃᶠᵃᵍᵃʰᵃⁱᵃʲᵃᵏᵃˡᵃᵐᵃⁿᵃᵒᵃᵖᵃᵠᵃʳᵃˢᵃᵗᵃᵘᵃᵛᵃʷᵃˣᵃʸᵃᶻᵇᵃ
