The Talmud asks: If, according to the opinion of R' Akiva, we are not concerned that the meat might spoil, let us sacrifice the daily offering at 6½ hours, as there are many Paschal lambs and no voluntary vow or free-will offerings to be sacrificed. Why, then, should they postpone the daily offering? The Talmud responds that R' Akiva holds: The additional offerings precede the bowls and therefore the priest would sacrifice the additional offerings at 6 hours, and offer the bowls at 7 hours, and then sacrifice the daily offering at 7½ hours.
מתקיף לה רבה בר עולא: מידי ״כסידרו בחול כך סידרו בשבת בערב הפסח, דברי רבי ישמעאל״ קתני?! ״כך סידרו בשבת״ סתמא קתני?
Rabba bar Ulla strongly objects to this explanation. Does the baraita teach: Like the arrangement of the daily offering during the week, so is its arrangement on Shabbat that occurs on Passover eve; this is the statement of R' Yishmael? The baraita simply teaches: So is its arrangement on Shabbat. Rava’s explanation also fails to correspond to the wording of the baraita.
אלא אמר רבה בר עולא, הכי קתני: כסידרו בחול דעלמא — כך סידרו בשבת דעלמא, דברי רבי ישמעאל.
Rather, Rabba bar Ulla said: The baraita should be understood as referring not to the eve of Passover, but to the rest of the days of the year, and this is what it is teaching: Like its arrangement on an ordinary day during the week, so is its arrangement on an ordinary Shabbat, at 8½ hours; this is the statement of R' Yishmael, who maintains that there is no distinction at all in this regard between Shabbat and a weekday.
רבי עקיבא אומר: כסידרו בערב הפסח דעלמא — כך סידרו בשבת דעלמא. ומתניתין דקתני בין בחול בין בשבת — דברי הכל היא.
R' Akiva says: Like its arrangement on an ordinary Passover eve that occurs on a weekday, at 7½ hours, so is its arrangement on an ordinary Shabbat. Since no free-will offerings are offered on Shabbat, the daily offering can be sacrificed earlier. And the Mishnah, which teaches that the daily offering on Passover eve is slaughtered at the same time, whether during the week or on Shabbat, can be said to be in agreement with all opinions, both that of R' Yishmael and that of R' Akiva.
