Shavua tov, Rabotai. Boker or u'mevorach. Today, we continue our study in the ongoing series of Bekiim B'Halacha, dedicated to the memory of Chaim ben Mazal, with a prayer for his complete recovery. We are currently on day 95, examining page 257 of Abekim Malacha 5. In our previous discussions, we explored a significant machloket between the Kabbalists and the Talmudists regarding the tefillin of Rashi and Rabbeinu Tam. The Talmudists view this dispute as one where either Rashi's or Rabbeinu Tam's tefillin is correct, but we cannot definitively determine which is right. The minhag, or custom, is to follow Rashi, but to err on the side of caution, the Talmudists suggest that one should wear both tefillin separately or together, with the intention that whichever is correct fulfills the mitzvah, and the other is merely straps. Alternatively, one could put them on sequentially if space is limited.
This perspective aligns with the teachings of the chachamim of the Talmud and is reflected in the Shulchan Aruch, as well as in the interpretations of many Rishonim, including the Rashba, Ramban, Rabbeinu Yonah, and even the Rambam. The consensus among most Rishonim is that one tefillin is correct, and the other is not. Conversely, the Kabbalists assert that both tefillin are valid and complement each other, thus necessitating the wearing of both to properly fulfill the mitzvah of tefillin. The Ben Ish Chai strongly supports this view, citing early Kabbalistic sources, including Rabbeinu Ha-Ari, and claims that Moshe Rabbeinu wore two tefillin, providing evidence for this practice.
We are not here to persuade you in either direction regarding this machloket; that choice is yours. However, we aim to explore another machloket that arises from this initial debate: which of the two tefillin—Rashi's or Rabbeinu Tam's—is considered higher or more sanctified? According to the Kabbalists, Rabbeinu Tam's tefillin are viewed as superior. When worn, they are positioned higher than Rashi's, both on the head and the arm. The reasons behind this elevation are rooted in Kabbalistic teachings, which we may not fully comprehend, but the belief persists that Rabbeinu Tam's tefillin hold a higher status.
In light of this perspective, the Ben Ish Chai rules that it is forbidden to repurpose straps or housings of Rabbeinu Tam's tefillin for Rashi's, as this would constitute a downgrade. For instance, if one wishes to switch the boxes, Rabbeinu Tam's to Rashi's, this is not permissible. The principle of ma'alin bakodesh v'ein moridin applies here, meaning one should elevate in holiness and not diminish it. The same applies to switching straps or even the kuratcha, as it could lead to using Rabbeinu Tam's tefillin in a manner that is not befitting their higher sanctity.
However, Chacham Ovadia, of blessed memory, disagrees with the Ben Ish Chai, suggesting that Rabbeinu Tam's tefillin are not inherently superior. According to his view, if one wishes to upgrade from Rashi's to Rabbeinu Tam's, it is permissible since it is an elevation. The prohibition lies only in downgrading from Rabbeinu Tam's to Rashi's. Thus, according to Chacham Ovadia, one cannot mix and match either tefillin, as the Talmudists would argue that we cannot determine which one is obligatory and which is not.
Chacham Ovadia emphasizes that the Talmud validates only one type of tefillin, implying that the Kabbalistic leniency suggested by the Ben Ish Chai does not hold weight against the Talmudic consensus. The Talmud's stance is clear: once a tefillin is designated for a specific purpose, it should not be altered. This leads us to the halachic conclusion that one cannot change the battim or retzuot from one type of tefillin to another, as stated in the halacha: "Asur leshanot habattim retzuot." This applies equally to all components of tefillin, including the kuratcha.
In a practical case, if someone mistakenly placed the parshiyot of Rabbeinu Tam in the box designated for Rashi, and this error was discovered only after the tefillin had been used for the mitzvah, the Shevet HaLevi posits that it would be permissible to replace the parchments with those written for Rashi's tefillin. His reasoning is that the boxes do not assume the identity of Rabbeinu Tam's tefillin due to the lack of intention at the time of use. Other poskim have ruled similarly, allowing for the use of items designated for Rabbeinu Tam after they have been used for Rashi's tefillin.
Even with new tefillin that have never been worn, if one stipulates their intention before using the straps or scrolls, it is permissible to switch between Rashi's and Rabbeinu Tam's tefillin. This stipulation is crucial, as it establishes the user's intent. However, the Mishnah Berurah cautions against changing items even with a prior stipulation, while the Kaf HaChaim cites opinions that permit such changes, suggesting that the Mishnah Berurah may have been lenient had he known of these later opinions.
We now turn to a common scenario: using your kuratcha for mundane items. The Gemara discusses the concept of hazmanah and sarbeh, where hazmanah refers to designating an item for a specific purpose, and sarbeh involves actual use. If one designates a kuratcha for tefillin and subsequently places tefillin inside, it becomes prohibited to use that kuratcha for any mundane items thereafter. The Gemara states that once it has been designated and used for tefillin, it cannot be used for anything less than tefillin, such as a mezuzah.
However, if either condition is lacking—meaning if the kuratcha was designated but not used, or vice versa—it remains permissible to use it for mundane purposes. The halachic principle here clarifies that the prohibition only applies when both conditions are met: permanent designation and actual use. If the designation was temporary, it does not carry the same weight, and thus one may switch to mundane use.
It is essential to note that if one has designated a bag for tefillin without specific stipulations, it is generally assumed to be a permanent designation. The Eliahu Vilna ruled that unless otherwise specified, the designation is considered permanent. This leads us to the understanding that one must be cautious about how they designate items for sacred use, as it can have lasting implications.
In summary, when engaging with the complexities of tefillin, one must be mindful of the distinctions between Rashi's and Rabbeinu Tam's tefillin, the sanctity of the items used, and the implications of switching or reusing components. Each decision carries halachic weight, and understanding these nuances ensures proper observance of the mitzvah.
