It is reasonable to assume that in the case of the act being performed in ignorance of the Sabbaths and with knowledge of its prohibition he had no doubt at all that the intervening week-days effected separateness, and that his question was only when the act was performed with the knowledge of the Sabbaths but in ignorance of its prohibition, [the point in doubt being] whether different Sabbaths are like different objects or not. His reply was that in the case of the act being done with knowledge of the Sabbaths but in ignorance of its prohibition the different Sabbaths were like different objects. This reply, however, he [R. Akiba] did not accept. He then proved that secondary acts of work were on a par with principal acts of work, but this too he rejected. Said Rabbah: Whence do I derive this? From that which we have learnt: ‘A great general rule has been laid down with regard to Sabbath: He who was altogether oblivious of the principle of Sabbath and performed many acts of work on many Sabbaths, is liable to one offering only. If he knew the principle of Sabbath and did many acts of work on many Sabbaths, he is liable for each Sabbath. If he knew each time that the day was Sabbath, and did many acts of work on many Sabbaths, he is liable for each principal act of work’. Now, it does not say, ‘he is liable for each principal act of work and for each Sabbath’. Whom does [the Mishnah] follow? Shall I say R. Eliezer? Read then the latter clause: ‘If he did many [secondary] acts of work of the same [principal] class, he is liable only to one offering’; but according to R. Eliezer he should be liable for each of the secondary acts of work as if they were principal acts of work! Hence it is clear [that this Mishnah, then, represents] R. Akiba's view, and it is hereby proved that he had no doubt at all that in the case of an act being done in ignorance of the Sabbath and with knowledge of its prohibition the intervening week-days effected separateness, and that his question was only when the act was performed with knowledge of the Sabbath but in ignorance of its prohibition, the point being whether different Sabbaths are like different objects or not. The other's solution was that they were like different objects, and that secondary acts were on a par with principal acts of work; but both answers were rejected by him. Said Abaye to him: Indeed I maintain that R. Akiba had no doubt that different Sabbaths were not comparable to different objects in the case where an act was done with knowledge of the Sabbath but in ignorance of its prohibition; and his question was only in the case where an act was done in ignorance of the Sabbath but with knowledge of its prohibition, [the query being] whether the intervening week-days effected separateness or not. The solution offered was that the intervening week-days effected separateness, and this was accepted by him; he also ruled that secondary acts of work were on a par with principal acts of work, but this was rejected by him. Rab Hisda said: In the case of an act being done with knowledge of the Sabbath but in ignorance of its prohibition even R. Akiba agrees that the different Sabbath days are like different objects; but his query was whether the intervening week-days effected separateness in the case where an act was done in ignorance of the Sabbath but with knowledge of its prohibition. The other's solution was that the intervening week-days effected separateness; and this was accepted by him. He also ruled that secondary acts of work were on a par with principal acts of work, but this was rejected by him. Said Rab Hisda: Whence do I derive this? From that which has been taught: ‘If one wrote [on Sabbath] two letters in one spell of unawareness, he is liable [to an offering]; if in separate spells of unawareness, Rabban Gamaliel says: He is liable; and the Sages say: He is not. Rabban Gamaliel, however, admits that if he wrote one letter on one Sabbath and the other on another, he is exempt’. Whereas in another [Baraitha] it has been taught: ‘If one wrote two letters on two different Sabbaths, one on one Sabbath and the other on another, Rabban Gamaliel declares him liable, and the Sages declare him not liable’. On the assumption that Rabban Gamaliel followed R. Akiba's opinion, [Rab Hisda argued thus:] According to me, who hold that in the case of an act being performed with knowledge of the Sabbath but in ignorance of its prohibition even R. Akiba agrees that the different Sabbath days are like different objects, there is no contradiction, for that which taught that he is exempt refers to a case where the letters were written with knowledge of the Sabbath but in ignorance of the prohibition, in which case the different Sabbaths are like different objects 21ᵃᵇᶜᵈᵉᶠᵍʰⁱʲᵏˡᵐⁿᵒᵖᵠʳˢᵗᵘ
