to reach down to the bottom and thus serve as a substitute for the wall by application of the law of "Gud Achith." Cannot the same rule apply to two sides of a house? Let the edge of the roof on both sides be supposed to reach down to the bottom? Said the disciples of Rabh in the name of their master: "The Mishna refers to a house where the corner walls had fallen in and where the roof was not flat but slanting, so that with the walls it also fell."
Samuel said: "In the case of a court the Mishna does refer to an instance where the breach exceeded ten ells, but it also states that the walls had caved in on both sides because further, when treating of a house, it must specify two sides, hence it does so also when courts are in question." Why must two sides be mentioned in the instance of a house? Cannot the edge of the roof be supposed to reach down to the bottom of both walls? Then again does Samuel hold to the supposition, that the edge of the roof reaches to the bottom of the wall? Was it not taught that concerning a gallery in a valley, Rabh said, it is permitted to carry throughout the whole extent of the valley, because the edges of the gallery are supposed to reach down to the ground and thus form a partition for the entire valley, whereas Samuel maintained that this supposition cannot be considered and hence it is only permitted to carry for a distance of four ells? This would not present a difficulty, for in that case Samuel maintains, that the edges of the gallery must not be supposed to reach down to the ground because there must be four distinct partitions, but where only three are necessary he would admit the feasibility of such a supposition. The difficulty concerning the two sides of the house where the breach measured over ten ells still remains! In the same manner as the disciples of Rabh referred to a house where the corner walls had fallen in together with their slanting roof, Samuel may refer to a house, the corner walls of which had sustained a breach four ells in width on each corner, or eight ells in all, and five ells in length on one side, and five ells and a trifle on the other side, or slightly over ten ells in all. Hence it would be necessary to suppose that the edges of the roof reach down on four sides of the breach two in width and two in length and that would be contrary to the theory of Samuel!
Why does Samuel not hold with Rabh? Because the Mishna does not mention a slanting roof and Rabh does not hold with Samuel because he (Rabh, as we have seen in the instance of the gallery in the valley) permits of the supposition, that the edges of a gallery or a roof can reach down on four sides.
"R. Jose said: If it were permitted for that particular Sabbath," etc. The schoolmen propounded a question: "How is R. Jose's dictum to be construed? Does he mean to permit it entirely or to prohibit it entirely?" R. Shesheth as well as R. Johanan said: "He means to prohibit it entirely." We also learned to this effect in a Boraitha, viz.: R. Jose said: As they are not permitted to carry on subsequent Sabbaths, so are they also prohibited to do so on that particular Sabbath.
It was taught: R. Hyya bar Joseph said, the Halakha prevails according to R. Jose, and Samuel said: "The Halakha prevails according to R. Jehudah. Did Samuel indeed say so?" Did not R. Jehudah reply to R. Hana of Bagdad that Samuel decreed: "The Halakha prevails according to R. Jehudah in all cases pertaining to Erubin, but not where partitions are concerned?" Said R. Anan: "Samuel himself explained to me that if the courts were laid open towards unclaimed ground the Halakha prevails according to R. Jehudah but if they were laid open towards public ground the Halakha prevails according to R. Jose."
MISHNA: If an attic be built over two houses, also if bridges are open at both ends, it is lawful to carry things underneath on the Sabbath. Such is the dictum of R. Jehudah; but the sages prohibit it. Moreover, R. Jehudah further said: It is lawful to combine, by means of an Erub, an alley that is open at both ends, but the sages prohibit it.
GEMARA: Said Rabba: Do not say that the reason of R. Jehudah is because a private ground requires according to biblical law only two partitions, but because he holds (Gud Achith) that the ends of the roofs (in this case of the attic or the bridge) are supposed to reach down to the bottom.
CHAPTER X.
SUNDRY REGULATIONS CONCERNING THE SABBATH.
MISHNA: If a man (on Sabbath) find tephilin (on the road), he should match them and bring them (into the nearest town or village) in single pairs (i.e., one for the head and one for the arm). Rabbon Gamaliel said: "He may bring in two pair at a time." To what does this rule apply? To old tephilin (phylacteries), but if they be new, he need not bring them in (at all). If he find them tied up in pairs, or all tied together, be should remain with them till dark and then bring them in. In times of danger (religious persecutions), however, he covers them up and passes on. R. Simeon said: He should hand them to his companion (i.e., the man standing next to him), who in turn hands them to his companion, and so on from hand to hand until the outmost court is reached. So, likewise, his child, he should hand it to his companion, who in turn hands it to his companion and so on from hand to hand, even (if it have passed through the hands of) an hundred (men), R. Jehudah said: "In like manner, a man may pass a cask of wine (which he has found on the road on the Sabbath) to his companion, and he in turn to his companion (and so on from hand to hand) even beyond the legal limits; the sages, however, objected: "The cask cannot be conveyed further than its owners have the right to walk."
GEMARA: He may only carry them in single pairs? Shall we assume that this anonymous Mishna is not in accordance with R. Meir, who decrees (Tract Sabbath, page 257) that a man may clothe himself in as many garments as he chooses? Said Rabba: In both instances the decree of R. Meir is based upon the custom of the week-days (when a man may also put on as many clothes as he chooses), and as the above-mentioned Mishna treats of "saving from fire" the Rabbis permit a man to wear as much clothing as he chooses. In this instance, however, where there is no danger, (and as a man only wears one pair of tephilin on a week-day, hence he may wear only one pair on a Sabbath). Thus this Mishna can also be in accordance with the decree of R. Meir.
"Rabbon Gamaliel said: He may bring in two pair." What is the reason of R. Gamaliel's dictum? Does he hold, that on Sabbath also tephilin should be worn? Then he should only have permitted one pair to be brought in? If, however, he holds that on Sabbath tephilin should not be worn and it is merely to save the tephilin that it was permitted for a man to wear them on his head and arm, why does he only permit two pair at a time; he could have permitted more? Said R. Samuel bar R. Itz'hak: "On the head there is only room for two." On the hand, however, there is room for but one? As there is room for two on the head, according to R. Samuel, there is room for two also on the arm.
Shall we say that the first Tana of the Mishna differs with Rabbon Gamaliel upon the point advanced by R. Samuel bar R. Itz'hak maintaining that there is only room for one on the head or arm while R. Gamaliel holds there is room for two? Nay; all agree that there is room for two, but they differ as to the legality of wearing tephilin on the Sabbath. The first Tana holds that they should be worn on Sabbath, while Rabbon Gamaliel holds that they must not.
Who of the Tanaim ever held, that on Sabbath tephilin must be worn (in order that it might be said the first Tana of the Mishna is in accordance with his opinion)? That was R. Aqiba; as we have learned: It is written [Exod. xiii. 10]: "And thou shalt keep this ordinance in its season from year to year." And elsewhere [Tract Menachoth] where there is a dispute between R. Jose the Galilean and R. Aqiba, it concludes with the statement that R. Aqiba holds the wearing of tephilin on Sabbath to be legal. Does R. Aqiba indeed hold that Sabbath is (also) a proper time for the wearing of tephilin? Have we not learned in another Boraitha as follows: R. Aqiba said: "Lest we should assume that it is required to wear tephilin on Sabbath or on festivals, it is written [ibid. 9]: 'And it shall be unto thee for a sign upon thy hand,' which means, that tephilin should be worn, when a sign is required, but Sabbath and festivals being signs in themselves, it is not necessary to have another. "Therefore we must say, that the first Tana of our Mishna does not hold according to R. Aqiba but in accordance with the Tana of the following Boraitha: "He who stays awake at night may either wear tephilin or not, so said R. Nathan; Jonathan Qitoni, however, said: 'It is not allowed to wear tephilin at night.'" If R. Nathan, then, holds that tephilin may be worn at night, he also holds, that they may be worn on Sabbath. This is no evidence! It may be that he holds
