an incomprehensible explanation.
CHAPTER IX.
REGULATIONS CONCERNING THE COMBINING OF ROOFS ON SABBATH.
MISHNA: All the roofs of a town are considered one private ground (although the houses underneath are occupied by several), provided there be not one roof ten hands higher or ten hands lower than the rest. Such is the dictum of R. Meir; the sages, however, hold, that each roof constitutes a separate private, ground. R. Simeon said: Roofs, as well as courts and wood-stores, constitute one private ground, for the carrying of all such utensils as were actually situated there when the Sabbath set in, but not for the carrying of such utensils as were still in the house, when the Sabbath set in.
GEMARA: Abayi bar Abhin and R. Hanina bar Abhin were sitting alongside of Abayi, and were conversing between themselves: "It is right according to the sages, who hold, that, in the same manner as the houses are separated below, so are also the roofs above; thus, unless an Erub is made between the houses, it is not permitted to carry from one roof to the other; but what is the opinion of R. Meir? Does he hold, that as the houses are separated so are also the roofs, why does he state, that all the roofs constitute one private ground; or if he holds that above ten spans there is nothing but private ground, what difference does it make to him, whether a roof be ten spans higher or lower than the rest?" Said Abayi to the two brothers: "Have ye not heard the dictum of R. Itz'hak bar Abhdimi to the effect, that R. Meir said thus: 'Where there are two distinct premises both of which, however, are legally private ground, e.g., a pillar, ten spans high and four spans wide standing in private ground, and which must not be used to shoulder burdens thereon on the Sabbath, lest a heap of the same size standing in public ground be used for the same purpose,' so it is also in this case, where a roof is ten spans lower or higher than the rest the same precautionary measure applies."
The two brothers hearing this from Abayi thought, that according to R. Meir the same case applied to a mortar or kettle, ten spans high; said Abayi to them: "My master told me, that R. Meir said, this precaution applied only to a pillar and a millstone because for these two objects special places are designated, but as for other utensils, even if they be ten spans high, the precaution is unnecessary."
"The sages, however, hold, that each roof constitutes a separate private ground." It was taught: Rabh said: "On every roof things must not be handled except within a limit of four ells," but Samuel said: "They may be handled in the whole extent of the roof." If the roofs are separated and the separation is apparent, all agree, that carrying things on those roofs is permissible (because in this case the walls underneath are considered as if they reached up to the tops of the roofs) but they differ concerning roofs that are separated, where the separation is not apparent. Rabh holds that things must not be carried on those roofs (where the separation is not apparent) except for a distance of four ells, because he does not admit, in this case, the theory of Gud Assik (possibility of the walls reaching up to the tops of the roofs), while Samuel, who does admit the theory, holds, that carrying is permitted in the entire extent of the roofs (because he admits of the possibility of the walls reaching the tops of the roofs).
An objection was made based upon our Mishna: The sages hold, that each roof constitutes a separate private ground. This is in accordance with Samuel's opinion but is contradictory to the opinion of Rabh. The disciples of Rabh said in his name, that the statement, "things must not be handled except within a limit of four ells," meant to signify, "two ells in each adjoining roof" (but in the one roof things may be handled throughout its entire extent).
Abayi said: "If a man erected an attic on top of his house and provided it with a small door four spans wide, he may carry things in all the roofs." (The reason for this statement is, that the fact of the man having made an attic and provided it with a door is proof, that the other inmates had resigned their right to the use of the roof in his favor.) Said Rabha: "It may happen, that the small door with which the attic was provided may prevent the man from using the other roofs" (even according to R. Meir). How so? If the door in the attic faced a garden below and the partition made by the attic separated his roof from the others, it might be said, that he made that door merely so as to be able to watch his garden and renounced his right to the use of the roofs. (It was taught:) Roofs, level one to the other in which, according to R. Meir, it is permitted to carry things, and a single roof which may be used according to the sages, may according to Rabh be used throughout their whole extent, while according to Samuel, it is only allowed to use them for an extent of four ells. Would not this be a contradiction by Rabh to his previous statement and by Samuel to his own former dictum? This can be explained thus: Rabh's previous statement referred to a case, where the separation between the roofs was not apparent while in this case the separation is apparent and Samuel's former dictum referred to a roof that had less than two saahs' capacity, while in this case it refers to a roof that has a capacity of more than two saah. Why should a roof of that size not be allowed to be used? The possibility of the walls reaching the tops of the roofs is not admitted, for the reason that partitions which enclose dwellings are made downwards and are not supposed to extend upwards, and of a space which is not enclosed by partitions of dwellings and has a capacity of over two saah, only four ells may be used.
It was taught: Concerning a ship, Rabh said, one may carry things throughout the whole extent of the ship, because the space of a ship is enclosed with partitions, and Samuel said, one may carry only to the extent of four ells. Why so? Because the partitions were not made for the purpose of making the space inhabitable but merely to keep out the water. Said R. Hyya bar Joseph to Samuel: "According to whose opinion does the Halakha prevail? According to thy opinion or according to Rabh's," and Samuel answered, "The Halakha prevails according to Rabh."
R. Giddel in the name of R. Hyya bar Joseph said: "Rabh agrees with Samuel's opinion, concerning a ship that was in dry dock and turned over, that it was only permitted to carry things for a distance of four ells." For what purpose was the ship turned over? If people lived within it, why should it not be allowed to carry things throughout its whole extent? Is the bottom of the ship not equal to a roof, when the ship was turned over? Nay; the ship was turned over for a coating of tar.
R. Jehudah said: When we shall arrive at the final conclusions of R. Meir we shall find that all roofs are considered as one private ground in their own right, i.e., that carrying from one roof to the other is permissible; also that all courts are considered as one private ground and likewise all woodsheds, but from the final conclusions of the sages we shall learn, that roofs and courts constitute one private ground, i.e., that it is permitted to carry things from the roof to the court and vice versa, which, according to R. Meir is not allowed. The woodsheds, however, are considered according to the sages a separate private ground, i.e., things may be carried from one woodshed to another but not from a woodshed into a court. The final conclusions of R. Simeon denote, that all roofs, courts, and woodsheds are considered as one private ground.
We have learned one Boraitha in support of Rabh and another in support of R. Jehudah. The one supporting Rabh reads as follows: "All roofs of the town are considered as one private ground; but it is prohibited to carry things from the roofs to the courts, and vice versa." Vessels which were situated in the court before the Sabbath set in, may be carried in all the courts, and those situated in the roofs before the Sabbath set in may be handled in all the roofs, provided there is not a roof ten spans higher or lower than the rest. Such is the dictum of R. Meir; but the sages said: Every roof constitutes a separate ground and things must not be carried in it for a distance of over four ells. This bears out the statement of Rabh in which he says that when the separation between the roofs is not apparent one must not carry except in a limit of four ells.
In support of R. Jehudah we have learned the following Boraitha: Rabbi said: "When we learned the Law at R. Simeon's in the city of Thequa, we would carry towels and oil from one roof to another, from that to the court, and from that to another, and from the other court to a woodshed, and from that to another, until we would come to the springs where we would bathe."
Said R. Jehudah: "It happened in a time of danger, that we brought up the sacred scrolls
