In our study of the halachot derived from the Daf, we will focus specifically on Daf Nun Bet, examining the relevant psakim from the Shulchan Aruch. We will begin with the halacha as outlined in Siman Kuf Samech Zayin and Kuf Samech Vav. The first point of discussion is whether one needs to be concerned about an interruption, or hefsek, between netilat yadayim and HaMotzi. Some authorities, as noted, state that one does not need to worry about a hefsek after performing netilat yadayim. Conversely, others hold that one should indeed avoid interruptions between these actions, and it is advisable to take care in this matter.
What constitutes a hefsek? If one waits the duration it takes to walk twenty-two ammah, which is approximately 45 to 50 feet, this is considered a hefsek according to Maran. Therefore, one must be cautious about this timing.
Next, we turn to halacha vav, which states that before one performs mayim acharonim, they should ensure the table is clean, so that no crumbs remain. This is to prevent the crumbs from becoming dirty when the water is poured over them. Although it is permitted to discard crumbs that are less than a kezayit, there is concern that a shamash—an attendant who may be an am ha'aretz—could accidentally leave crumbs that are a kezayit on the table. According to Beit Hillel, it is permissible to use a shamash who is an am ha'aretz, but one should still be cautious of leaving crumbs that are a kezayit on the table, as it is forbidden to discard them by hand.
Thus, it is recommended to clean the table beforehand. However, in contemporary practice, we do not follow this caution as strictly since we do not remove tables as was customary in earlier times. Today, we perform mayim acharonim outside of the table, and therefore do not have crumbs to worry about. Additionally, we have designated dispensers for mayim acharonim, which further mitigates any potential issues.
In the times of the Talmud, there was a necessity to clean the area before mayim acharonim to avoid any pieces of bread that could be a kezayit remaining on the table. In contrast, our current practice does not necessitate such caution since we do not typically remove the table before the blessing. Nonetheless, we should be careful not to perform mayim acharonim over a location where there may be bread.
Chacham Ovadia notes that in the time of the Talmud, there was a greater concern for crumbs being left behind, as they could lead to a violation of the prohibition against discarding bread that is a kezayit. In our time, however, we are less strict, especially as we have adapted our practices to fit modern dining arrangements.
Moving on, we note that even though it is permissible to discard crumbs that do not contain a kezayit, one should still be cautious that no water from mayim acharonim falls on them, as this could lead to a violation of the prohibition against discarding bread. If one finds themselves with pieces of bread that are less than a kezayit, they should ideally store them until they can be disposed of properly, such as placing them in a bag to be discarded later.
As we transition to Siman Reish Tzadik Vav, halacha alef discusses the requirements for Havdalah. It is essential to ensure that the cup used is not pagum, meaning it should not have been drunk from prior to the blessing. According to the Rambam, the mitzvah of Havdalah is a biblical commandment, akin to Kiddush, and must be performed with a full cup. If someone has already drunk from the cup, it cannot be used for Kiddush or Havdalah as it is considered pagum.
The Rema further elaborates on customs surrounding Havdalah, noting that it is customary to recite certain psukim before performing Havdalah. Although these recitations are not obligatory, they enhance the ritual. At the time of Havdalah, one should look at the cup and the candle, and it is customary to pour a bit of wine on the ground after the blessing.
In the case where one does not have wine or grape juice for Havdalah, they may use beer, which is classified as chamar medina. The order of preference for Kiddush and Havdalah is wine first, followed by grape juice, and then beer. If neither wine nor grape juice is available, one may use bread to fulfill the obligation of Kiddush on Friday night, performing Netilat Yadayim beforehand.
It is essential to understand the halachic distinctions regarding the use of various beverages for Kiddush and Havdalah. For example, if a person is away and cannot access wine, they may squeeze grapes to create grape juice, which is acceptable. However, if one finds themselves without any wine or bread, they cannot eat until they perform some form of Kiddush.
On Shabbat morning, it is critical to note that while some communities have the custom of making Kiddush on whiskey, this is not the ideal practice if wine or grape juice is available. The halacha prioritizes wine or grape juice for Kiddush, and the use of whiskey should be reserved for situations where no grape products are available.
In summary, our exploration of the halachot derived from Daf Nun Bet emphasizes the importance of understanding and adhering to these distinctions in practice, thereby enhancing our observance and appreciation of the mitzvot associated with Kiddush and Havdalah.
