Arukh HaShulchan, Orach Chaim 209:10-210:3

The sugya before us, as elucidated by the Arukh HaShulchan (AH) in Orach Chaim 209:10-210:3, presents a fascinating confluence of foundational principles: the chiyuv (obligation) of Talmud Torah as it pertains to brachot, and the intricate halachot of zimun, particularly regarding the inclusion of ketanim (minors) in a minyan for Shem Hashem. The AH, with his characteristic blend of psak and rigorous lomdus, navigates these waters, often charting a course that challenges common understanding while remaining firmly rooted in classical sources. This analysis will delve into his interpretations, uncover the underlying sevarot, and explore the friction points with other poskim.

Text Snapshot

The Arukh HaShulchan presents his chiddushim with clarity and force. Two lines particularly capture the essence of his approach in these sugyot:

1. On the Chiyuv to Learn Brachot:

   "ולא מצינו שום מצוה שיהא האדם חייב ללמוד אותה אם אינו יודע אלא מצות ברכה, וזאת ללמד שחייב כל אדם ללמוד לברך ואם אינו לומד מבטל מצוה." (Arukh HaShulchan, Orach Chaim 209:11) Dikduk/Leshon Nuance: The emphatic "ולא מצינו שום מצוה שיהא האדם חייב ללמוד אותה אם אינו יודע אלא מצות ברכה" (we do not find any mitzvah where a person is obligated to learn it if he doesn't know it, except the mitzvah of bracha) is a powerful assertion. The phrasing "מבטל מצוה" (negates a mitzvah) implies a more severe transgression than merely being exempt or unable to fulfill it. It highlights an active failure to acquire the necessary knowledge. This is a profound statement about the unique nature of brachot and the chiyuv Talmud Torah inherent in them.

2. On the Exclusion of a Katan from Zimun b'Shem Hashem:

   "אלא דעת רוב הפוסקים וכן נראה עיקר דקטן אינו מצטרף לזימון בשם אף שמבין." (Arukh HaShulchan, Orach Chaim 210:3) Dikduk/Leshon Nuance: The phrase "דעת רוב הפוסקים וכן נראה עיקר" (the opinion of most poskim and so it appears to be the main opinion) indicates a strong, decisive psak on the part of the AH, even when going against the Rema (as will be discussed). The addition of "אף שמבין" (even if he understands) directly addresses and refutes the primary sevara for including a katan – that of chinuch (education) for a katan who comprehends the mitzvah. This sets the stage for a fundamental disagreement on the nature of davar sheb'kedusha and the role of ketanim.

Readings

The Arukh HaShulchan's discussion is rich with intertextual dialogue, engaging with Rishonim and Acharonim alike. We will explore several key voices that shape his analysis.

The Rambam's Foundational Chiyuv to Learn Brachot

The Arukh HaShulchan's assertion in OC 209:11, that the mitzvah of brachah uniquely imposes an obligation to learn it if one is ignorant, finds its undercurrent in the Rambam's systematic codification. The Rambam establishes the chiyuv of Birkat HaMazon as mi'deoraita (from the Torah) in Hilchot Brachot 1:1, derived from the verse "וְאָכַלְתָּ וְשָׂבָעְתָּ וּבֵרַכְתָּ אֶת ה' אֱלֹקֶיךָ עַל הָאָרֶץ הַטֹּבָה אֲשֶׁר נָתַן לָךְ" (Devarim 8:10). This foundational chiyuv lays the groundwork for the stringency attached to its performance.

Crucially, the Rambam also discusses the nusach (text) of brachot. In Hilchot Brachot 1:6, he states, "כל הברכות כולן... חייב לזכור בהן השם והמלכות" (All brachot... one must mention in them God's Name and Kingship) and further in 1:12, he codifies the specific nusach for Birkat HaMazon. The Rambam's chiddush is in emphasizing that the mitzvah is not merely to express gratitude, but to do so via a specific, Chazal-ordained text and formula. This implies that simply having kavanah (intention) without the correct words is insufficient for fulfilling the mitzvah. If the mitzvah requires a specific nusach, then knowing that nusach becomes an integral part of fulfilling the mitzvah.

The Arukh HaShulchan leverages this. If the Rambam considers the specific nusach an indispensable component of the mitzvah, then the lack of knowledge of that nusach is not merely an unfortunate circumstance, but a direct impediment to kayim (fulfilling) a deoraita mitzvah. Hence, the chiyuv to learn the nusach transforms from a general chiyuv Talmud Torah into a specific, active chiyuv to enable the performance of this particular mitzvah. The AH's chiddush is in making this explicit: the Rambam's insistence on specific nusach for a deoraita mitzvah necessitates an active chiyuv to learn that nusach, a chiyuv he posits is unique in its directness among mitzvot. One cannot simply say "I don't know" and be exempt; rather, the chiyuv is "ללמוד לברך" (to learn to bless) or, failing that due to an insurmountable obstacle, "לשמוע מאחר" (to hear from another)¹.

The Rosh on Birkat HaMazon as Mi'deoraita and its Ramifications

The Rosh (Rabbeinu Asher ben Yechiel), in Piskei HaRosh to Berachot 7:20, explicitly states that Birkat HaMazon is mi'deoraita. While this is a widely accepted position, the Rosh's emphasis on it, particularly when discussing the chiyuv of women, underlines the gravity of the mitzvah. He argues that women are obligated in Birkat HaMazon because it is a mitzvah aseh she'eina zman grama (a positive commandment not bound by time), and thus they are equally obligated as men.

The Rosh's chiddush, from the perspective of our sugya, lies in connecting the deoraita status directly to the stringency of the chiyuv to perform the mitzvah correctly. If Birkat HaMazon is a Torah-level obligation, then any impediment to its proper performance, such as ignorance of its text, is a significant issue. This reinforces the AH's position that active steps must be taken to overcome such ignorance. The Rosh's approach thus provides a strong halachic bedrock for the AH's unique chiyuv to learn brachot. The greater the chiyuv from the Torah, the greater the chiyuv to acquire the means to fulfill it. The very idea that one could simply be "exempt" from a deoraita mitzvah due to ignorance, without a prior chiyuv to overcome that ignorance, would be problematic from the Rosh's perspective. The Arukh HaShulchan's insistence on learning or having another bless is a natural extension of this deoraita stringency.

Rema & Magen Avraham: The Katan in Zimun b'Shem Hashem for Chinuch

The most prominent point of friction in the AH's discussion of zimun is his stance on including a katan for zimun b'Shem Hashem (when ten or more have eaten together). The Shulchan Aruch (OC 210:2) states that "עשרה שאכלו יחד אומר המזמן נברך א-להינו שאכלנו משלו" (Ten who ate together, the leader says, 'Let us bless our God from whose [bounty] we have eaten'). The Rema (ibid.) adds a crucial gloss: "וי"א דאפי' יש תשעה גדולים וקטן אחד המבין, מצטרף לעשרה" (And some say that even if there are nine adults and one katan who understands, he can be joined to make ten). This psak of the Rema is widely followed.

The Magen Avraham (OC 210:3) explains the Rema's reasoning: "נראה דכיון דמבין שפיר ויודע לברך, אף דקטן הוא, מכל מקום לצרפו לעשרה כדי שיהא זימון בשם הוי כמצוה דרבים וזמנין דעושין כן כדי לחנכו" (It seems that since he understands well and knows how to bless, even though he is a katan, nevertheless, to join him for ten so that there will be zimun with God's Name is like a mitzvah of the many, and sometimes they do so in order to educate him).

The chiddush of the Rema and Magen Avraham is the introduction of the chinuch (education) principle into the calculation of a minyan for davar sheb'kedusha. Typically, a katan is not counted for any davar sheb'kedusha (e.g., Kaddish, Kedusha, Borchu) because he is not bar chiyuva (obligated in mitzvot)². The Magen Avraham suggests that zimun b'Shem Hashem, while involving God's Name, is perhaps not a davar sheb'kedusha in the same rigorous sense as tefillah b'tzibbur. Rather, it is an elevated form of hoda'ah (acknowledgement) that can be enhanced through chinuch. The katan is not motzi (fulfilling the obligation for) the adults, nor is he fundamentally part of the minyan in the full sense, but his participation (due to understanding) enables the adults to recite Shem Hashem as an act of public Kiddush Hashem that also serves his chinuch. This implies a more lenient view of zimun b'Shem Hashem vis-à-vis other davarim sheb'kedusha.

The Taz and Arukh HaShulchan: Strict Exclusion of the Katan

The Taz (Rabbi David HaLevi Segal), in Turei Zahav (OC 210:2), vehemently disagrees with the Rema. He writes: "אבל קטן אינו מצטרף לעשרה כלל לומר א-להינו, דהא כל דבר שבקדושה אין מצטרפין בו קטן" (But a katan is not joined for ten at all to say 'א-להינו,' for in any davar sheb'kedusha, a katan is not joined). The Taz's chiddush is a staunch defense of the general principle that a katan does not count for davarim sheb'kedusha. He sees no reason to distinguish zimun b'Shem Hashem from Kaddish or Kedusha. For the Taz, the inclusion of Shem Hashem elevates zimun to a full-fledged davar sheb'kedusha, making the katan's participation fundamentally invalid for the minyan.

The Arukh HaShulchan (OC 210:3) fully aligns with the Taz:

"ולא נהירא כלל. דהא קטן אין מצטרף לכל דבר שבקדושה כגון קדיש וקדושה וברכו, ואף על גב דמבין וגם ידע לברך... מכל מקום כיון דאין עליו חיוב מצות כלל אינו מצטרף לעשרה." (Arukh HaShulchan, Orach Chaim 210:3) (And this is not clear at all. For a katan is not joined for any davar sheb'kedusha such as Kaddish, Kedusha, and Borchu, and even though he understands and also knows how to bless... nevertheless, since he has no chiyuv mitzvot at all, he is not joined for ten.)

The AH's chiddush here is multifaceted. First, he explicitly rejects the Rema's svara of "מבין" (understanding) and "יודע לברך" (knows how to bless) as insufficient. The core criterion, he argues, is "אין עליו חיוב מצות כלל" (he has no chiyuv mitzvot at all). A katan is fundamentally not bar chiyuva, and therefore cannot contribute to a minyan that requires chiyuv for its validity. Second, he brings the Yerushalmi (Berachot 7:4) as a definitive proof: "אמר רב הונא בר חייה אמר רבי ירמיה קטן אין מצטרף לזימון" (Rav Huna bar Chiya said in the name of Rabbi Yirmiya, a katan is not joined for zimun). While the Yerushalmi might refer to the basic zimun of three, the AH extrapolates it to zimun b'Shem Hashem, arguing that if a katan cannot be part of the fundamental zimun, he certainly cannot be part of its more elevated form requiring Shem Hashem. The AH's position represents a rigorous, principled adherence to the definition of davar sheb'kedusha and the halachic status of a katan.

Friction

The most significant point of contention within this sugya is the question of including a katan in zimun b'Shem Hashem to complete a minyan of ten. The Rema (OC 210:2) permits it if the katan understands, a position widely codified, particularly by the Magen Avraham (OC 210:3) for reasons of chinuch. The Taz (OC 210:2) and, following him with considerable force, the Arukh HaShulchan (OC 210:3) categorically reject this, asserting that a katan cannot be counted for davar sheb'kedusha.

The Strongest Kushya

The fundamental kushya against the Rema's position (and by extension, the Magen Avraham's defense of it) is straightforward: How can a katan, who is not bar chiyuva (obligated in mitzvot) and thus cannot be counted for davarim sheb'kedusha like Kaddish or Kedusha, be counted for zimun b'Shem Hashem? The phrase "א-להינו" explicitly invokes God's Name, elevating the zimun to a level requiring a full minyan of bnei Torah (obligated individuals). If zimun b'Shem Hashem is a davar sheb'kedusha, then the general rule, reiterated by the Taz and Arukh HaShulchan, should apply unequivocally: a katan is excluded. To allow it seems to compromise the very definition of a minyan for davarim sheb'kedusha. Furthermore, the Arukh HaShulchan's citation of the Yerushalmi (Berachot 7:4), "קטן אין מצטרף לזימון," appears to be a direct refutation even of the basic inclusion of a katan for zimun, let alone b'Shem Hashem. The Yerushalmi's blanket exclusion of ketanim from zimun seems to leave no room for the Rema's leniency.

The Best Terutz (or Two)

The terutz for the Rema's position must address the nature of zimun b'Shem Hashem and the role of chinuch.

Terutz 1: Distinguishing the Nature of Zimun b'Shem Hashem

One primary terutz, implicit in the Magen Avraham's explanation, is that zimun b'Shem Hashem is not a davar sheb'kedusha in the same sense as Kaddish or Kedusha. These latter davarim are communal prayers or declarations that are intrinsically dependent on a minyan of bnei chiyuva for their very existence. Without ten bnei chiyuva, they simply cannot be recited. Zimun, however, is fundamentally an invitation to bless, which exists even for three adults. The addition of "א-להינו" for ten is an enhancement (הוספה) or a hiddur (beautification) of the zimun, turning it into a more public Kiddush Hashem by formally invoking God's Name. It's not that the zimun becomes a davar sheb'kedusha requiring ten bnei chiyuva to create it, but rather that the opportunity to recite Shem Hashem in a more elevated way arises when ten are present.

In this context, the katan is not being counted as a bar chiyuva to establish the minyan of ten. Rather, his presence and understanding (as required by the Rema) make him a fit subject for chinuch. The adults, who are bnei chiyuva, are present in sufficient numbers (nine adults) to constitute a group where the zimun itself is valid. The katan's role is not to complete the minyan in a strict sense, but to provide the context for the adults to say "א-להינו" through his participation in the broader dining group, for the sake of his chinuch. The Shem Hashem is recited by the adults, who are bnei chiyuva, and the katan's understanding and participation merely trigger this higher form of zimun as a takanah for chinuch.

This terutz suggests a spectrum of davarim sheb'kedusha. Some, like Kaddish, are absolute, requiring a minyan of bnei chiyuva as a prerequisite. Others, like zimun b'Shem Hashem, are expressions of kedusha that can be expanded or enhanced through the lens of chinuch, particularly when the core chiyuv (the zimun itself) is already established by adults. The Yerushalmi's statement, "קטן אין מצטרף לזימון," could be interpreted as referring to a katan leading the zimun or being counted as one of the fundamental three. It does not necessarily preclude his inclusion as a participant for chinuch when the greater minyan is forming around him.

Terutz 2: The Katan as a Catalyst, Not a Constituent Member

A slightly different nuance on the above terutz focuses on the katan as a "catalyst" for the Shem Hashem, rather than a constituent member of the minyan for davar sheb'kedusha. According to this view, the nine adults already have a chiyuv of zimun among themselves. When a katan who understands joins them, his presence, by virtue of the takanah of chinuch, allows the adults to say "א-להינו." He is not completing a minyan of ten bnei chiyuva for a davar sheb'kedusha. Instead, his presence simply changes the nusach for the bnei chiyuva who are already present. The chiyuv to say Shem Hashem is upon the adults, and the katan's presence is merely the condition that activates this higher nusach.

This is akin to a situation where a kohen might be present, allowing for Birkat Kohanim, even if he is not participating in the minyan for tefillah. The kohen's presence (or the katan's understanding and presence) is a condition for the performance of a mitzvah by others, not a counting towards the minyan itself. The Arukh HaShulchan and Taz strongly reject this distinction, viewing any inclusion of a katan for Shem Hashem as fundamentally invalid due to his non-bar chiyuva status. For them, zimun b'Shem Hashem is a unitary davar sheb'kedusha that requires ten bnei chiyuva, full stop.

Intertext

The sugyot concerning the chiyuv to learn brachot and the inclusion of ketanim in zimun resonate with broader halachic principles.

The Katan in Other Davarim Sheb'Kedusha (Minayn for Prayer)

The most direct and compelling parallel for the Arukh HaShulchan's stance on excluding a katan from zimun b'Shem Hashem is the general halacha regarding a minyan for communal prayers. It is a fundamental principle that a katan is not counted for a minyan for davarim sheb'kedusha such as Kaddish, Kedusha, Borchu, or Kriyat HaTorah³. This is because these davarim require ten bnei chiyuva – individuals who are obligated in mitzvot and capable of fulfilling the communal aspect. A katan, lacking this chiyuv, cannot contribute to the communal obligation.

The Mishnah Berurah (OC 55:12, s.v. Katan) reiterates this principle, stating that even if a katan is intelligent and understands, he cannot be counted. The Arukh HaShulchan himself (OC 55:16) discusses this extensively, emphasizing that davarim sheb'kedusha require gadlus (adulthood) and chiyuv mitzvot. His strong rejection of including a katan in zimun b'Shem Hashem (OC 210:3) directly draws on this established principle. The consistency of his approach highlights his view that zimun b'Shem Hashem belongs squarely within the category of davarim sheb'kedusha, where the katan's lack of chiyuv is an insurmountable obstacle. The Rema's leniency in OC 210:2 thus stands out as an anomaly that requires significant pilpul to reconcile with the broader halachic landscape.

The Katan for Kiddush and Havdalah

Another relevant intertext is the halacha regarding a katan being motzi (fulfilling the obligation for) adults in Kiddush and Havdalah. The Gemara in Sukkah 38a states, "קטן שהגיע לחינוך מוציא את הרבים ידי חובתן" (a katan who has reached the age of chinuch can fulfill the obligation of the many). This Gemara is typically understood in the context of Birkat HaMazon and other brachot, where the katan is motzi others who are chayav (obligated) in the bracha. However, there is a debate among poskim regarding Kiddush and Havdalah, which are mitzvot de'Rabanan (rabbinic commandments) but have an element of kedusha.

The Shulchan Aruch (OC 271:2) rules that "קטן שהגיע לחינוך, אפילו הוא בן שש או שבע, אם יודע לברך, מוציא את הרבים ידי חובתם בקידוש" (a katan who has reached the age of chinuch, even if he is six or seven, if he knows how to bless, can fulfill the obligation of the many for Kiddush). The Rema (ibid.) adds: "ויש חולקין וסבירא להו דאין קטן מוציא אלא גדולים שהם חייבים מדרבנן" (And there are those who disagree and hold that a katan only fulfills the obligation for adults who are obligated mi'deRabanan). This implies that for a mitzvah de'oraita or a davar sheb'kedusha with higher stringency, a katan cannot be motzi.

This sugya offers an interesting contrast. While a katan who understands can potentially be motzi adults for certain brachot or mitzvot de'Rabanan for chinuch purposes, this is usually limited. The debate around Kiddush highlights the tension: even for a mitzvah de'Rabanan with kedusha, some poskim are hesitant to allow a katan to be motzi adults. This strengthens the Arukh HaShulchan's position that for a davar sheb'kedusha like zimun b'Shem Hashem (which the AH considers more stringent than Kiddush), a katan's inclusion is untenable. The common thread is the katan's lack of chiyuv, which limits his ability to act as a full participant or facilitator for bnei chiyuva in contexts of elevated kedusha.

Psak/Practice

The Arukh HaShulchan's analyses in these sections lead to distinct practical conclusions and meta-psak heuristics.

The Chiyuv to Learn Brachot

The Arukh HaShulchan's emphatic assertion in OC 209:11 that the mitzvah of brachah uniquely imposes an obligation to learn it is a critical halachic and educational principle. The practical psak is clear:

1. Active Learning: Every adult is obligated to actively learn the correct nusach and halachot of brachot, especially Birkat HaMazon. Ignorance is not an excuse for exemption but rather a bitul mitzvah.
2. Proxy for the Unlearnable: If one is genuinely incapable of learning (e.g., due to mental incapacity, as mentioned in 209:12), they are like a katan and exempt. However, if they can learn but choose not to, they must have someone else bless for them. This means the chiyuv to perform the mitzvah remains, even if they cannot do it themselves. This lands as a fundamental meta-psak heuristic: for mitzvot that require specific knowledge (like brachot), the chiyuv extends to acquiring that knowledge. It underscores the centrality of Talmud Torah as a means to kayim mitzvot (fulfill commandments), not merely an end in itself.

The Katan in Zimun b'Shem Hashem

Here, the Arukh HaShulchan's psak (OC 210:3) aligns with the Taz and explicitly rejects the Rema and Magen Avraham. He rules that a katan, even one who understands, cannot be counted for zimun b'Shem Hashem. This means if there are nine adults and one katan, "א-להינו" should not be recited.

In practice, however, the halacha generally follows the Rema and Magen Avraham. Many contemporary poskim permit including an intelligent katan for zimun b'Shem Hashem for chinuch purposes, provided he is old enough to understand the meaning of the brachah. The Mishnah Berurah (OC 210:3) codifies the Rema's opinion, implicitly rejecting the Taz's stricture for practical halacha. This presents an interesting meta-psak heuristic: even when an Acharon like the Arukh HaShulchan presents a compelling sevara and cites strong sources (like the Yerushalmi), the accepted psak may lean towards a more lenient approach, particularly when rooted in chinuch and widely adopted by other influential poskim (like the Rema and Magen Avraham). The Arukh HaShulchan's strong stance here serves more as a powerful articulation of a specific lomdishe approach to davar sheb'kedusha than as a universally accepted final psak. One might even argue that the Magen Avraham's explanation of chinuch resonated more broadly with the halachic community, leading to its wider acceptance.

Takeaway

The Arukh HaShulchan's analysis underscores the intrinsic link between Talmud Torah and kabalat mitzvot, particularly for brachot, where ignorance is a failure, not an exemption. Simultaneously, his vigorous exclusion of the katan from zimun b'Shem Hashem highlights a rigorous definition of davar sheb'kedusha, prioritizing the chiyuv status of participants over educational leniencies, though this latter point is often tempered in practical halacha.
