Text Snapshot

The Rambam, with characteristic precision, opens by grounding the two-witness requirement in the Torah: "אֵין דִּין חוֹתְכִין בְּשׁוּם מִשְׁפָּט עַל פִּי עֵדוּת עֵד אֶחָד, לֹא בְּדִינֵי מָמוֹנוֹת וְלֹא בְּדִינֵי נְפָשׁוֹת, שֶׁנֶּאֱמַר (דברים יט, טו) 'לֹא יָקוּם עֵד אֶחָד בְּאִישׁ לְכָל עָוֹן וּלְכָל חֵטְא'. וּמִפִּי הַשְּׁמוּעָה לָמַדְנוּ שֶׁקָּם הוּא לִשְׁבוּעָה כְּמוֹ שֶׁבֵּאַרְנוּ בְּהִלְכוֹת טוֹעֵן וְנִטְעָן." (MT Eidut 5:1)

  • Dikduk/Leshon Nuance: "חוֹתְכִין" (lit. "cut/decide") – Steinsaltz notes this means "מכריעים" (decide/rule)11. The phrasing emphasizes the decisiveness of a court's ruling, which cannot rest on a single witness. "וּמִפִּי הַשְּׁמוּעָה" – Steinsaltz clarifies this refers to "מסורת חכמים במדרש הפסוקים" (the tradition of the Sages in interpreting the verses)12, a crucial point for understanding the Oral Law's derivation of halacha. The chiddush of ed echad for an oath is presented as a received tradition.

A particularly fraught line, sparking much lomdus, follows: "וְכָל מָקוֹם שֶׁעֵדוּת עֵד אֶחָד מוֹעִילָה, אִשָּׁה וּפָסוּל כָּשֵׁר לְהָעִיד כְּמוֹ כֵן. חוּץ מֵעֵד אֶחָד שֶׁקָּם הוּא לִשְׁבוּעָה. שֶׁאֵין מַשְׁבִּיעִין אֶלָּא עַל פִּי עֵדוּת כְּשֵׁרָה וְרְאוּיָה לְהִצְטָרֵף לְאַחֵר לְחַיֵּב מָמוֹן." (MT Eidut 5:3)

  • Dikduk/Leshon Nuance: The clause "חוּץ מֵעֵד אֶחָד שֶׁקָּם הוּא לִשְׁבוּעָה" is the crux. Rambam posits a unique exception: while a woman or pasul (disqualified person) can generally function as ed echad where ed echad is accepted (e.g., sotah, eidut isha), they cannot obligate an oath. The rationale provided is "שֶׁאֵין מַשְׁבִּיעִין אֶלָּא עַל פִּי עֵדוּת כְּשֵׁרָה וּרְאוּיָה לְהִצְטָרֵף לְאַחֵר לְחַיֵּב מָמוֹן" – the testimony must be "fit to be joined with another to obligate financial restitution." This implies a qualitative distinction in the nature of "testimony" that triggers an oath.

Readings

Kessef Mishneh's Query on MT 5:3

Rabbi Yosef Karo, in his Kessef Mishneh (KM), presents a foundational kushya on the Rambam's exclusion of women and pesulim from the ability to obligate an oath through ed echad. The general principle is "כל מקום שהאמינה תורה עד אחד אשה ופסול כשר להעיד" (wherever the Torah believes ed echad, a woman and a disqualified person are also fit to testify)13, derived from Yevamot 117a. If this principle holds, why should ed echad for an oath be an exception? The KM states: "ומה שכתב רבינו חוץ מעד אחד של שבועה כו' איני יודע מהיכן הוציא רבינו דין זה אם לא מדאמרינן לכל עון ולכל חטאת אינו קם אבל קם הוא לשבועה משמע דבראוי לעדות עון וחטאת בצירוף אחר עסקינן ע"כ."14 The KM speculates that perhaps the derivation from "לכל עון ולכל חטאת" implies that the ed echad must at least be of a type that could be a full witness (i.e., male, not disqualified) if joined by another. However, he offers this only as a tentative suggestion, indicating his own uncertainty regarding Rambam's source.

Tziunei Maharan's Defense and Elucidation

The Tziunei Maharan (Rabbi Yitzchak Isaac Chaver) vigorously defends Rambam against the KM's kushya, providing several robust proofs. He initially notes that the KM's proposed source is "דחוקין" (forced), as also remarked by the Noviy BeYahuda (Mahadura Kama, EH 33)15. The Tziunei Maharan argues that the very premise of the KM's kushya is flawed: the kal v'chomer (a fortiori argument) that since ed echad is believed for an oath, then women and pesulim should also be believed, overlooks a critical distinction. He posits that the chiddush of ed echad for an oath applies specifically to those who, were they two, would constitute valid eidut mamonot. Women and pesulim, by definition, can never form a valid pair for eidut mamonot. Thus, their "single witness" status cannot trigger an oath.

The Tziunei Maharan brings several proofs for Rambam's position:

  1. Ketubot 85a: The Gemara discusses Rava's court, where R' Papa testified that a shetar (document) was paid. Rava asked if there was another witness, and when R' Papa said no, Rava said, "אע"ג דאיכא מר ע"א לאו כלום הוא" (even though you are here, a single witness is nothing). R' Avina b. Mattana then asked, "ולא יהא ר"פ כבת ר"ח?" (Should R' Papa not be like Bat R' Chananya, who was believed as a single witness?). The Tosafot on Ketubot 85a16 interpret this to mean that R' Papa could have been a relative of the plaintiff or defendant, making him disqualified even for obligating an oath. This Tosafot directly supports Rambam's view that a relative (a type of pasul) cannot obligate an oath. The Tziunei Maharan elaborates that R' Papa's statement "מרענא שטרא אפומיה" (I invalidate the document based on my word) implies that the plaintiff would need to take an oath to collect, and even for this, R' Papa needed to be a kasher witness17.
  2. Shavuot 30a & 32b: The Gemara there discusses shevuat ha'edut (oath of testimony) and explicitly states that it does not apply to women, relatives, or pesulim (לא נוהגת לא בנשים ולא בקרובין ולא בפסולין)18. The Tziunei Maharan argues that if these individuals cannot obligate a korban oath in cases of shevuat ha'edut, then certainly they cannot obligate a standard oath in dinei mamonot. Rambam himself codifies this in Hilchot Shevuot 10:919.
  3. Torat Kohanim (Vayikra) and Yerushalmi Sotah 1:1: The Tziunei Maharan finds explicit support in these ancient sources. The Torat Kohanim states, regarding the requirement for hodaa (notification) to the sotah's husband: "אוציא את שאמרה לו אשה שאין אשה כשרה לעדות מניין אפי' אמרו לו קרובים... אוציא את שאמרו לו קרובים שאין כשרים להעיד בו מניין אפי' אמר לו עד אחד... אוציא את שאמר לו ע"א שאין מחייבו אלא שבועה"20. This text clearly distinguishes between types of single-witness scenarios and implies that a woman or relative cannot obligate an oath. Similarly, the Yerushalmi Sotah 1:1, discussing whether ed echad can make a sotah drink, engages in a kal v'chomer and explicitly states that a relative cannot obligate an oath ("וקאמר הירושלמי מה אם פיו שאינו זוקקו לשבועת ממון הרי הוא משקה עד אחד שהוא זוקקו לשבועת ממון לא כש"כ קרוב מהו שישקה כו' ומוכח דקרוב אינו יכול לחייב שבועה דאל"כ הא יש ללמוד גם קרוב בק"ו מפיו")21. These sources firmly establish that the chiddush of ed echad for an oath is limited to kasher witnesses.

Friction

The Kessef Mishneh's Strongest Kushya

The most potent kushya on Rambam's ruling in Hilchot Eidut 5:3, as articulated by the Kessef Mishneh, lies in its apparent contradiction of a widely accepted principle concerning ed echad. The Gemara in Yevamot 117a, in the context of eidut isha (testimony regarding a woman's husband's death), clearly states: "כל מקום שהאמינה תורה עד אחד אשה ופסול כשר להעיד" (wherever the Torah believed a single witness, a woman and a disqualified person are also fit to testify)22. This rule is a foundational tenet, allowing women and otherwise invalid witnesses to be believed in specific instances where the Torah relaxed the standard two-witness requirement.

Rambam himself, just two halachot prior (Eidut 5:2), cites eidut isha as a rabbinic application of ed echad, and then in 5:3, he states this general principle: "וְכָל מָקוֹם שֶׁעֵדוּת עֵד אֶחָד מוֹעִילָה, אִשָּׁה וּפָסוּל כָּשֵׁר לְהָעִיד כְּמוֹ כֵן." This makes his subsequent "חוּץ מֵעֵד אֶחָד שֶׁקָּם הוּא לִשְׁבוּעָה" (except for a single witness who obligates an oath) feel like a sharp departure, almost an internal contradiction. Why would the chiddush of ed echad for an oath—which already represents a relaxation of the two-witness rule—be more stringent than other ed echad scenarios, excluding women and pesulim? The very drasha that derives the halacha of ed echad for an oath from "לא יקום עד אחד באיש לכל עון ולכל חטאת" suggests that while it doesn't stand for all transgressions/sins, it does stand for some things, implying a certain leniency. To then impose a stricter qualification on the witness in this particular leniency seems counterintuitive and demands a clear textual source, which the Kessef Mishneh found lacking.

The Tziunei Maharan's Terutz

The Tziunei Maharan's robust defense of Rambam provides the strongest terutz by drawing a crucial distinction in the nature of "testimony" required for an oath. The key lies in Rambam's reasoning: "שֶׁאֵין מַשְׁבִּיעִין אֶלָּא עַל פִּי עֵדוּת כְּשֵׁרָה וּרְאוּיָה לְהִצְטָרֵף לְאַחֵר לְחַיֵּב מָמוֹן." This is not merely a witness for a specific function; it's a witness whose testimony, if joined by another, could lead to a full financial obligation.

The Tziunei Maharan argues that the chiddush of Yevamot 117a ("כל מקום שהאמינה תורה עד אחד אשה ופסול כשר להעיד") applies to situations where the ed echad is sufficient in its own right to achieve a certain outcome, albeit a relaxed one (e.g., sotah not drinking, eidut isha for remarriage). In these cases, the "testimony" is not about a potential monetary claim or punishment, but about a status or a preventative measure. Since the Torah itself, in these specific instances, does not require the full qualitative "witness" status of eidut mamonot/nefashot, it allows women and pesulim to fulfill that role.

However, the chiddush of ed echad for an oath is fundamentally different. It is derived from the pasuk that disqualifies ed echad for full eidut ("לא יקום עד אחד"). The interpretation that it does stand for an oath implies a partial validity of the witness, but a validity rooted in the potential for full eidut mamonot. The witness must be mechanically capable of being joined with another to form a beit din (court) for financial liability. Women and pesulim, by definition, cannot serve as valid witnesses in a full beit din for financial matters. Therefore, their "testimony" can never be "fit to be joined with another to obligate financial restitution." The Tziunei Maharan's reliance on Ketubot 85a (Tosafot), Shavuot 30a/32b, Torat Kohanim, and Yerushalmi Sotah 1:1, provides ample textual support for this nuanced understanding, demonstrating that this distinction is deeply embedded in Chazal's understanding of halacha. The Noviy BeYahuda's attempt to force a textual source for Rambam from Sifrei underscores the perceived difficulty, but Tziunei Maharan's composite of proofs effectively grounds Rambam's chiddush within the broader mesorah.

Intertext

Devarim 19:15 and its Drasha

The fundamental biblical source for the two-witness rule is Devarim 19:15: "לֹא יָקוּם עֵד אֶחָד בְּאִישׁ לְכָל עָוֹן וּלְכָל חֵטְא" (One witness shall not stand up against any person with regard to any transgression or any sin). The Oral Tradition, as stated by Rambam ("וּמִפִּי הַשְּׁמוּעָה לָמַדְנוּ"), derives the efficacy of ed echad for an oath from this very verse. The drasha (homiletical interpretation) focuses on the phrase "לְכָל עָוֹן וּלְכָל חֵטְא." The exclusion for all transgression/sin implies that while it doesn't stand to obligate punishment, it does stand for some lesser purpose—specifically, to obligate an oath23. This is a classic example of "מיעוט אחר מיעוט למעט" or similar exegetical principles, where a seemingly restrictive phrase is used to carve out an exception. The Noviy BeYahuda, as mentioned by Tziunei Maharan, attempts to locate a more explicit Sifrei source for this drasha relating to the specific exclusion of women/pesulim from the oath, though Tziunei Maharan finds his emendation of the Sifrei text problematic24.

Shulchan Aruch and the Silence of Codification

A significant intertextual observation comes from the Tziunei Maharan himself, who notes: "וְלֹא מָצָאתִי כָּעַת בְּטוּר וְשֻׁלְחָן עָרוּךְ חוֹשֶׁן מִשְׁפָּט שֶׁיַּעֲתִּיקוּ דִּין זֶה שֶׁל רַבֵּינוּ דְּאִשָּׁה אֵינָהּ יְכוֹלָה לְחַיֵּב שְׁבוּעָה"25 (I have not found at present in the Tur and Shulchan Aruch Choshen Mishpat that they copied this law of our Master that a woman cannot obligate an oath). This is a crucial nafka mina because the Shulchan Aruch is generally the bedrock of practical halacha. The omission of Rambam's stringency regarding women and pesulim for an oath suggests that Rabbi Karo (the author of Shulchan Aruch, and also Kessef Mishneh) did not accept Rambam's view on this point, or at least did not find it sufficiently compelling to codify. This could stem from his original kushya in the Kessef Mishneh for which he felt Rambam lacked a clear source. The Shut Rabbi Akiva Eiger (Siman 179), cited by Tziunei Maharan, brings the proof from Shavuot regarding shevuat ha'edut, indicating that the debate persisted among poskim26. This highlights the ongoing tension between a rigorous conceptual understanding of eidut (Rambam/Tziunei Maharan) and the need for clear, widely accepted codification (Shulchan Aruch).

Psak/Practice

The theoretical machloket between Rambam (as elucidated by Tziunei Maharan) and the Kessef Mishneh regarding the ability of women or pesulim to obligate an oath through ed echad has direct implications for halachic practice. Given the Tziunei Maharan's observation that the Shulchan Aruch (CM) does not explicitly codify Rambam's stricter view, the prevailing psak generally aligns with the more lenient position, accepting that a woman or pasul can indeed obligate an oath as ed echad in dinei mamonot. This reflects the Shulchan Aruch's role as the primary posek for the majority of Ashkenazim and Sephardim, and where it is silent on a stringency found in Rambam, it is often not adopted.

Beyond this specific point, other aspects of the Rambam's rulings in Hilchot Eidut 5-7 are fundamental and widely accepted in practice:

  • The principle of eidut batla miktzatah batlah kulah (MT 6:1-3) is a cornerstone of halacha regarding the invalidation of testimony and documents. If even one witness in a pair or group is disqualified (e.g., relative, pasul), the entire testimony is nullified, provided they all intended to testify. This applies equally to dinei mamonot and dinei nefashot.
  • The prohibition for a witness in dinei nefashot to then serve as a judge or even offer an opinion (MT 7:1) is a critical safeguard against bias and ensures judicial impartiality. This psak is universally accepted.
  • Conversely, the leniency in dinei de'rabanan (MT 7:2-3), allowing a witness to serve as a judge, is also standard practice. A common example, as Rambam gives, is two witnesses to a get (divorce document) joining a third person to form a beit din for its delivery.
  • The detailed five methods of kiyum shetarot (validation of documents) (MT 7:5-15) form the practical basis for authenticating signatures on legal documents in rabbinic courts. These are followed meticulously to ensure the integrity of financial and personal records.

Takeaway

The nuanced understanding of eidut reveals that the legal efficacy of a "witness" is not monolithic; ed echad has specific, often context-dependent, powers. The debate around women/pesulim and the oath highlights the subtle yet crucial distinctions in the very quality of testimony required for different halachic outcomes.
