Sukkah 47B

מאי לאו, זמן? לא, ברכת המזון ותפלה.

What, is it not that the blessing mentioned is the blessing of time, in support of the opinion of R' Yoḥanan? The Talmud rejects this possibility: No, the blessing here is Grace after Meals and the Amida prayer, where mention is made of the 8th Day of Assembly and not of Sukkot. Therefore, there is no support for the opinion of R' Yoḥanan that one recites the blessing of time on the 8th Day of Assembly.

הכי נמי מסתברא, דאי סלקא דעתך זמן ⁠— זמן כל שבעה מי איכא? הא לא קשיא: דאי לא בריך האידנא ⁠— מברך למחר, או ליומא אחרינא.

The Talmud says: So too, it is reasonable that this is the proper understanding of the baraita, as should it enter your mind that the baraita is referring to the blessing of time, is there a blessing of time all 7 days of Sukkot? One recites the blessing only on the 1st day. The Talmud responds: This is not difficult, and that is no proof that the baraita is not referring to the blessing of time, as the baraita could mean that if one did not recite the blessing today, on the 1st day, he recites the blessing on the next day or on another day of the Festival. Under those circumstances the blessing of time may be recited on any of the 7 days.

מכל מקום כוס בעינן! לימא מסייע ליה לרב נחמן, דאמר רב נחמן: זמן אומרו אפילו בשוק. דאי אמרת בעינן כוס ⁠— כוס כל יומא מי איכא? דלמא דאיקלע ליה כוס.

The Talmud asks: How could one recite the blessing of time on each of the days of Sukkot if in any case we require the blessing to be recited over a cup of wine, and not everyone has access to wine during the intermediate days of the Festival? From the fact that the Talmud does not consider this factor, let us say that this baraita supports the opinion of Rav Naḥman, as Rav Naḥman said: One recites the blessing of time even in the marketplace, without wine, as, if you say that we require a cup of wine in order to recite the blessing of time, is there a cup of wine available every day that would enable one to recite the blessing during the intermediate days of the Festival? The Talmud rejects this proof: Perhaps the baraita is referring to a case where a cup of wine happened to become available to him. The baraita is not describing the preferred method of reciting the blessing but merely a possibility.
