1 Rabbah stated: What is Rab's reason? Because the man did not specify the exact spot. Others read: Rabbah stated: What is Rab's reason? Because he is of the opinion that what cannot be acquired in succession cannot be acquired even simultaneously. What is the practical difference between them? The practical difference between them is the case where a man said: ‘Let me acquire an area of four cubits out of the eight’. According to him who read: ‘Because the man did not specify the exact spot’ [such a statement is invalid, for here], surely, he did not specify the exact spot; but according to him who read: ‘What cannot be acquired in succession cannot be acquired even simultaneously’ such [a statement is valid] as [if an area of] four cubits [had been indicated] for here the man spoke of acquiring [no more than] four cubits. [Turning to] the main text: Rabbah stated: ‘What cannot be acquired in succession cannot be acquired even simultaneously’. Abaye raised all objection against Rabbah: If a man gives excessive tithes, his produce is well prepared but his tithes are spoilt. But why? Should it not be said: ‘What cannot be acquired in succession cannot be acquired even simultaneously’? — Tithe is different, since it is applicable to fractions; for if a man said: ‘Let a half of every wheat grain be consecrated’ it becomes consecrated. But is not the tithe of cattle inapplicable to fractions and ineffective in succession and yet Raba ruled: If two abreast came out tenth, and they were both designated as tithe, the tenth and the eleventh are a mixture of holy and profane? — The tithing of cattle is different, since in a case of error it is applicable in succession, for we have learnt: If the ninth was named tenth, and tenth ninth, and the eleventh tenth, all the three are consecrated. But is not a thanksgiving offering invalid in a case of error as well as in one of succession, and yet it was stated: If the slaying of a sacrifice of thanksgiving was accompanied by all offering of eighty loaves, Hezekiah ruled: Forty out of these eighty are consecrated, and R. Johanan ruled: Forty out of eighty cannot be consecrated? — Surely, in connection with this it was stated: R. Joshua b. Levi explained: All agree that [forty of the loaves] are consecrated where the donor said: ‘Let forty out of the eighty be consecrated’; and no one disputes the ruling that none of the loaves is consecrated where he said: ‘The forty shall not be consecrated unless all the eighty are consecrated’; they only differ where the donor made no stipulation whatever, in which case one Master is of the opinion that his intention was to assure [the safety of the prescribed number] and that he brought the additional loaves conditionally only; 35ʰʲˡʳˢʷˣʸᵃᵃᵃᵇᵃᶜᵃᵈᵃᵉᵃᶠᵃᵍᵃʰᵃⁱ

2 while the other Master holds the view that the donor's intention was to provide a generous offering. Abaye stated: This was learnt only in respect of a tree the diameter underneath which was [no less than] twelve cubits but in the case of a tree the diameter underneath which was less than twelve cubits, behold a part at least of the man's house is well marked out. R. Huna son of R. Joshua demurred: Whence is it proved that he has at all intended the middle four cubits? Is it not possible that he intended either the four cubits on the one side or the four on the other side? Rather, said R. Huna son of R. Joshua: This was learnt only in respect of a tree the diameter underneath which was [no less than] eight cubits, but in the case of a tree the diameter underneath which was only seven cubits, behold a part at least of his house is well marked out. It was taught in agreement with Rab and it was also taught in agreement with Samuel. ‘It was taught in agreement with Rab’: If a man who was on a journey [homeward] was overtaken by dusk, and he knew of a tree or a wall and said: ‘Let my Sabbath base be under it’, his statement is of no avail, but if he said: ‘Let my Sabbath base be in such and such a place’ he may continue his journey until he arrives at that place. Having arrived there he may walk throughout its interior and along a distance of two thousand cubits beyond it. This, however, applies only to a well defined spot as, for instance, a mound that was ten handbreadths high and from four cubits to two beth se'ah in area, or a valley that was ten handbreadths deep and from four cubits to two beth se'ah in area, but where the place is not well defined he is not allowed to move more than four cubits. If two were [travelling together] and one of them knows [of a well defined place] and the other does not know of it, the latter transfers his right to choose a place to the former who then declares, ‘My Sabbath base shall be in such and such a place’. This only applies where the man had indicated the four cubits he selected by a mark, but if he did not indicate the four cubits he had selected by any mark he must not stir from his place. Must it be said that this presents an objection against Samuel? Samuel can answer you: Here we are dealing with a case where from the place on which the man stood to the root of the tree there were two thousand and four cubits, so that if you were to put him on the further side of the tree he would be standing outside his permitted limit; hence, if he indicated four cubits [on the near side of the tree] he may proceed thither, otherwise he may not. ‘It was taught in agreement with Samuel’: If a man made a mistake and prepared ‘erubs in two opposite directions, believing that it is permitted to provide ‘erubs in two opposite directions, or if he said to his servants, ‘Go and prepare an ‘erub for me’ and one prepared for him an ‘erub in a northerly direction and the other prepared one for him in a southerly direction, he may proceed northwards as far as the limit of his southern ‘erub and southwards as far as the limit of his northern ‘erub. But if they measured each limit exactly he may not stir from his place. Must it be said that this presents an objection against Rab? — No; Rab is a Tanna and is privileged to differ. IF, HOWEVER, HE SAID LET MY SABBATH BASE BE AT ITS ROOT’, HE MAY WALK FROM THE PLACE WHERE HE STANDS TO ITS ROOT A DISTANCE OF TWO THOUSAND CUBITS, AND FROM ITS ROOT TO HIS HOUSE ANOTHER TWO THOUSAND CUBITS. THUS HE CAN WALK FOUR THOUSAND CUBITS AFTER DUSK.ᵃʲᵃᵏᵃˡᵃᵐᵃⁿᵃᵒᵃᵖᵃᵠᵃʳᵃˢᵃᵗᵃᵘᵃᵛᵃʷᵃˣᵃʸᵃᶻᵇᵃᵇᵇᵇᶜᵇᵈᵇᵉᵇᶠᵇᵍᵇʰᵇⁱᵇʲᵇᵏᵇˡᵇᵐᵇⁿᵇᵒᵇᵖᵇᵠᵇʳᵇˢᵇᵗᵇᵘᵇᵛᵇʷᵇˣᵇʸᵇᶻ
