Zevachim 81

Sugya Map

This sugya on Zevachim 81a grapples with fundamental principles of sacrificial law (avodat hakorbanot), particularly concerning the handling of mixed blood (damim me'uravim) and the interpretive methodologies behind halakhic derivations.

Issues

• The Nature of Mixed Sacrificial Blood: Does mixed blood retain its original identity and fitness for avodah, or does it become disqualified? This hinges on the concept of ro'in (viewing improperly placed blood as water) and bitul (nullification).
• The Scope of Bal Tosif: How does the prohibition of "do not add" (Devarim 13:1) apply when mixed blood is presented on the altar? Specifically, if one places a measure of blood that combines elements from multiple offerings, is this an addition?
• Distinction Between Bilul and Kosos: Is there a halakhic difference between blood actually mixed (bilul) versus cups of blood merely intermingled (kosos) where the contents are unknown?
• Equivalence of Blood Placement Locations: Are the placement locations for shiyarei chatat (remainder of a sin offering's blood) and dam olah (blood of a burnt offering) identical, or distinct? This impacts cases of mixed remainders.
• Sources for Ein Bitul B'damim Ha'Olim L'Mizbeach: The Gemara explores various derashot for the principle that blood eligible for the altar is not nullified when mixed with other such blood.

Nafka Mina(s)

• Permissibility of Avodah: Whether mixed blood (e.g., chatat and olah blood, or pesulei mukdashim with kesherim) can be placed on the altar, or if it must be poured into the drain.
• Sanctity of Sacrifices: The extent to which the kedusha of sacrificial blood persists through mixing.
• Methodological Interpretation: The sugya highlights machloket Tannaim regarding derashot and the very definition of machloket (e.g., R' Yehuda's statement aliba d'R' Eliezer).
• Application of Bal Tosif: The practical implications of bal tosif in ritual contexts, specifically concerning the amount of blood placed.

Primary Sources

• Mishna (Zevachim 81a): The starting point, presenting the dispute between R' Eliezer and the Rabbis regarding mixed blood of a chatat (above the red line) and olah (below the red line).
• Gemara (Zevachim 81a): Elaborates on the Mishna, introducing Rava's distinction, R' Yehuda's baraita, and the Abaye/Rav Yosef debate.
• Vayikra 1:5: "והקריבו בני אהרן את הדם וזרקו את הדם" – Source for ein bitul from the repetition of "דם".
• Vayikra 6:23: "וכל חטאת אשר יובא מדמה אל אוהל מועד לכפר בקדש לא תאכל" – Source for pigul of chatat blood brought lifnim.
• Vayikra 7:7: "כחטאת כן האשם" – R' Eliezer's source for equating asham to chatat regarding disqualification.
• Vayikra 16:18: "ולקח מדם הפר ומדם השעיר" – Another source for ein bitul.
• Bamidbar 18:17: "קודש הם" – A third source for ein bitul concerning bechorot.
• Vayikra 27:26: "הוא יהיה קדש" – Source for the din of a bechor's temura.

Text Snapshot

The sugya opens by addressing a kushya on R' Eliezer's position in the Mishna (Zevachim 80b), which permits placing mixed blood by "viewing" the improperly placed portion as water:

וכי תימא הכא נמי בנתערב ארבע במתנה אחת אי הכי הכא בל תוסיף מהיכא? הרי אין כאן מן הבכור אלא כדי מתנה. And if you would say that here too [in our Mishna], it is referring to a case where four placements [of a burnt offering's blood] were mixed with one placement [of a firstborn's blood], if so, from where is the violation of "do not add" here? After all, there is only enough from the firstborn's blood for one placement. Zevachim 81a:1

This hava amina (initial assumption) attempts to reconcile R' Eliezer's view with bal tosif. The Gemara's question, "הכא בל תוסיף מהיכא" (from where is bal tosif here?), highlights the problem: if only one matana (placement) is needed from the bechor's blood, and that amount is present, how can one transgress bal tosif by placing it, even if mixed? This implies a specific understanding of bal tosif related to quantity and intent.

The Gemara then presents Rava's crucial distinction:

אלא אמר רבא לא נחלקו רבי אליעזר ורבנן בנתערב. מתי נחלקו? בתערובת כוסות. Rather, Rava says: Rabbi Eliezer and the Rabbis do not disagree with regard to [actual blood] mixed together. When they disagree it is with regard to cups [of blood] that were intermingled. Zevachim 81a:2-3

Rava's chiddush (novel interpretation) redefines the scope of the machloket. He posits that the Mishna's dispute only applies to kosos (intermingled cups where one doesn't know which is which), but not to bilul (actual mixing of blood). According to Rava, in bilul, everyone agrees the blood is sacrificed. This chiddush is immediately challenged:

והא לא פליגי בנתערב? והתניא ר' יהודה אומר לא נחלקו ר"א וחכמים על דם חטאת שנתערב בדם עולה שיקרב, ועל דם נבעל ומרבע שישפך. על מה נחלקו? על דם תמים שנתערב בדם בעל מום, שר"א אומר יקרב בין בנתערב בין בתערובת כוסות, ורבנן אומרים לא יקרב. And do they not disagree with regard to blood mixed together? But isn't it taught in a baraita: Rabbi Yehuda said: Rabbi Eliezer and the Rabbis did not disagree in a case of blood of a sin offering that was mixed with blood of a burnt offering that the mixture shall be sacrificed, or in a case of blood that was fit for presentation that was mixed with the blood of an animal that copulated with a person, or an animal that was the object of bestiality, that it shall not be sacrificed. With regard to what case did they disagree? With regard to blood of an unblemished animal that was mixed with blood of a blemished animal, as Rabbi Eliezer says that it shall be sacrificed, whether in a case of blood mixed together or in a case of intermingled cups, and the Rabbis say it shall not be sacrificed. Zevachim 81a:7-9

This baraita appears to contradict Rava directly. R' Yehuda states that everyone agrees that chatat mixed with olah blood shall be sacrificed (יקרב) – implying no dispute in bilul. However, R' Yehuda then states that the machloket does apply to bilul and kosos when tamim blood (unblemished) is mixed with ba'al mum blood (blemished). This complex baraita needs careful unpacking to understand the true scope of R' Eliezer's and the Rabbis' disagreement, especially concerning bilul.

Later, Abaye introduces another machloket regarding the equivalence of blood placement locations:

אמר אביי לא שנו אלא חטאת ראשונה ועולה. אבל חטאת אחרונה ועולה, כ"ע לא פליגי דמקום עולה היינו מקום שיריים. Abaye says: They taught [that the blood is poured into the drain] only if the first portion of the blood of a sin offering and a burnt offering were mixed. But if the final portion of the blood of a sin offering [shiyarei chatat] and a burnt offering were mixed, everyone agrees that since the place of the blood of a burnt offering is the same as the place of the remainder [of the sin offering], the priest shall place all the blood on the side of the altar below the red line. Zevachim 81a:12

Abaye asserts that shiyarei chatat (poured onto the yesod - base) and dam olah (sprinkled below the red line) share the same ultimate location, thus permitting their mixture. Rav Yosef disputes this, arguing that shiyarei needs the karkov (bench) and is distinct. This machloket about mkom shiyara is pivotal for understanding how different types of blood interact.

Readings

The sugya on Zevachim 81a is a labyrinth of interconnected arguments concerning mixed sacrificial blood, the principle of ro'in, and the application of bal tosif. The Rishonim offer varying lenses through which to navigate its complexities.

Rashi: Reconciling Bal Tosif and Ro'in

Chiddush: Rashi clarifies the initial hava amina's challenge of bal tosif by explaining its specific application to the quantity of blood, and then elucidates Rava's distinction between bilul and kosos as a means to resolve the underlying Mishnaic dispute.

Rashi's commentary is foundational for understanding the Gemara's flow. On the opening hava amina regarding bal tosif (Zevachim 81a s.v. "וכי תימא הכא נמי"), Rashi explains the Gemara's initial attempt to interpret the Mishna. The Mishna on 80b discusses dam bechor (one placement) mixed with dam olah (four placements). R' Eliezer permits the placement of the mixture, "viewing" the olah portion placed in the bechor's single placement as water. The Gemara's hava amina here (81a) suggests that even if one places five placements (four for the olah, plus one for the bechor), R' Yehoshua's kushya of bal tosif is not apparent. Why? Because the bechor's portion is only enough for one placement. If one takes a measure that could contain both, and places it once, where is the bal tosif? This is because "הרי אין כאן מן הבכור אלא כדי מתנה" (Zevachim 81a s.v. "הכא בל תוסיף מהיכא") – there is only enough bechor blood for one matana. Rashi's insight is that bal tosif here is understood as adding to the quantity of the required matana from a specific type of blood. If the bechor blood itself is only enough for one matana, placing that matana doesn't constitute an addition from the bechor's perspective, even if it contains olah blood. This reading suggests that the bal tosif concern applies to the specific blood and its required matanot, not merely the aggregate volume.

Subsequently, Rashi explains Rava's groundbreaking distinction between bilul (actual mixing) and kosos (intermingled cups) (Zevachim 81a s.v. "אלא אמר רבא"). Rava argues that R' Eliezer and Rabbanan only dispute in kosos. In such a case, R' Eliezer says to perform the avodah with each cup, "viewing" the "extra" as water, because we don't know which cup contains which blood. The Rabbis, lacking the principle of ro'in, require pouring it all into the drain. However, in bilul, Rava claims everyone agrees that the blood is sacrificed. Rashi clarifies that Rava's statement implies that in bilul, there is no problem of bal tosif or disqualification, presumably because the bloods become a single entity, and their kedusha is not lost. This sets up the Gemara's challenge from R' Yehuda's baraita, which directly contradicts Rava by showing a machloket even in bilul. Rashi's elucidation highlights how Rava attempts to narrow the scope of the Mishna's machloket to preserve the kesherut of mixed blood in most scenarios.

Tosafot: The Nuance of Bal Tosif and Probabilistic Doubts

Chiddush: Tosafot challenges Rashi's interpretation of bal tosif in the initial hava amina, proposing that even in a seemingly simple case, a safek (doubt) of bal tosif can arise due to the potential for dividing a single matana into multiple placements, thereby introducing a chiddush about safek bal tosif in ritual.

Tosafot (Zevachim 81a s.v. "הג"ה בל תוסיף מהיכא") directly questions Rashi's explanation of bal tosif. Rashi had said that if there is only enough bechor blood for one matana, there is no bal tosif. Tosafot retorts: "תימה לי הלא במתנה אחת של בכור אי אפשר שלא יוכלו לחלק לשתים" (Zevachim 81a s.v. "הג"ה בל תוסיף מהיכא") – it's difficult to say that one matana of bechor blood cannot be divided into two. If it can be divided, perhaps one places from it into two corners, thereby transgressing bal tosif (as the bechor only needs one placement). Even if there's no bilah (mixing), the safek (doubt) arises: did one place additional blood from the bechor beyond its single requirement? This is a sophisticated kushya, suggesting that bal tosif can be triggered not just by a definite addition, but by a safek of addition when the blood is divisible.

Tosafot then offers a terutz: "וי"ל דיש שיעור לשתי קרנות וכיון דאין בילה אין כאן רק ספק בל תוסיף ומשום ספק זה לא יניח קרבנו ואפילו כי הוה נמי דמים מעורבים יחד הוה ספק והכי פריך נהי דנתערב ארבע באחד לא תיקשי מאין בילה אכתי [תיקשי] קושיא אחריתי דלא מתרץ דבל תוסיף בודאי ליכא" (Zevachim 81a s.v. "הג"ה בל תוסיף מהיכא"). The terutz is that there is enough blood for two corners. However, since there's no bilah (actual mixing, according to the hava amina which assumes R' Eliezer doesn't acknowledge mixing), it's only a safek bal tosif. The Gemara's kushya of "from where is bal tosif here" implies a certain bal tosif, not a mere safek. Tosafot's analysis pushes the understanding of bal tosif beyond a simple quantitative addition to include the qualitative aspect of whether the blood itself is definitively designated for a single matana or can be construed as multiple matanot. This highlights a key tension: does safek bal tosif preclude ritual action, or is it overridden by the need to perform the avodah? In this context, the Gemara seeks a definite bal tosif.

Tosafot further elaborates on a different interpretation of bal tosif, suggesting it refers to "שיריים של בכור" (remainder of bechor blood) or "שיריים בשביל עולה" (remainder for the olah). This reveals the layered interpretations of bal tosif within the sugya, emphasizing its complex application in avodat hakorbanot.

Rambam: Codifying the Principles of Ro'in and Bitul

Chiddush: Rambam codifies the halakha that R' Eliezer's principle of ro'in is rejected, and that damim ha'olim l'mizbeach do not nullify one another, thereby establishing the normative practice derived from the sugya.

Rambam, in Hilchot Ma'aseh HaKorbanot, directly addresses the conclusions of our sugya. He adopts the position of the Rabbis against R' Eliezer's ro'in. In Hilchot Ma'aseh HaKorbanot 5:10, Rambam states: "דם הקרבנות שנתערבו זה בזה, אם היו כולם ראויין להקרבה, הרי הן קרבים." (Mishneh Torah, Hilchot Ma'aseh HaKorbanot 5:10). This directly reflects the Gemara's conclusion that "דם העולים למזבח אינן בטלין זה בזה" (blood that ascends to the altar is not nullified by one another). This general rule applies when bloods of the same type or similar types (e.g., two olahs) are mixed, or even chatat and olah as per R' Yehuda's baraita. Rambam's use of "אם היו כולם ראויין להקרבה" (if all were fit for offering) is critical.

However, Rambam then delineates exceptions and specifics. He states that if dam chatat (above the line) and dam olah (below the line) are mixed, and there is no bitul (nullification) between them, the halakha follows the Rabbis: "חטאת ועולה שנתערבו דמיהן, ישפכו לאמה. ואם זרקן למעלה, פסול; למטה, פסול. שאין דם חטאת עולה למטה, ודם עולה אינו עולה למעלה" (Mishneh Torah, Hilchot Ma'aseh HaKorbanot 5:11). This directly contradicts R' Eliezer's position in our Mishna (Zevachim 80b) and implicitly rejects his ro'in principle. The mixture is disqualified because neither blood can properly fulfill its avodah in the other's location. This confirms that R' Eliezer's ro'in is lo halakha. Rambam's codification here underscores the Rabbis' emphasis on strict adherence to the prescribed locations for blood placement, even in mixed scenarios.

Furthermore, Rambam addresses the dispute about shiyarei chatat and dam olah. He rules in Hilchot Ma'aseh HaKorbanot 5:12: "דם שיריים של חטאת שנתערב בדם עולה, אם היו שניהם ראויין למקום אחד, כגון שיריים של חטאת החיצונה, ועולה, הרי הן נזרקין למטה." (Mishneh Torah, Hilchot Ma'aseh HaKorbanot 5:12). This aligns with Abaye's view that their places are the same, allowing their mixture to be placed. Rambam then adds: "אבל שיריים של חטאת הפנימית, שנתערבו בדם עולה, ישפכו לאמה." This distinction highlights that while shiyarei chatat chitzona (external altar) and olah share a location, shiyarei chatat p'nimit (inner altar) do not. This reflects Rav Yitzchak bar Yosef's terutz in the sugya to Rav Huna bar Yehuda's objection (Zevachim 81b). Rambam's precise distinctions reveal his careful synthesis of the Gemara's various machloket and terutzim into a coherent halakhic framework.

Ritva: Delineating the Scope of the Machloket and Ro'in

Chiddush: Ritva provides a comprehensive analysis of Rava's distinction between bilul and kosos, clarifying the specific contexts in which R' Eliezer's ro'in principle applies, and exploring the implications of R' Yehuda's baraita for the understanding of machloket Tannaim.

The Ritva (Zevachim 81a s.v. "אלא אמר רבא") delves deeply into Rava's explanation that the machloket between R' Eliezer and the Rabbis is only in kosos (intermingled cups), not in bilul (actual mixing). Ritva explains that the reason R' Eliezer applies ro'in in kosos is because there's a safek as to which cup contains the valid blood. By placing all the cups, and "viewing" the invalid portions as water, he ensures the valid blood is placed without bal tosif or pesul. The Rabbis reject ro'in entirely, hence they require pouring it all out. However, in bilul, Ritva explains Rava's view to be that everyone agrees the blood is pasul if the bloods are of different categories (e.g., chatat and olah), because the mixture itself creates a problem that ro'in cannot solve. This is a subtle yet significant departure from the apparent simplicity of Rava's initial statement as understood by Rashi, which seemed to suggest bilul was always kasher. Ritva suggests Rava intends that bilul is kasher only where the avodah is the same for both, but not if the avodot are distinct.

Ritva then grapples with the baraita of R' Yehuda, which appears to contradict Rava's initial assertion. R' Yehuda states that chatat and olah blood mixed "יקרב" (shall be sacrificed), implying bilul is permitted. Ritva clarifies that R' Yehuda's statement "לא נחלקו ר"א וחכמים על דם חטאת שנתערב בדם עולה שיקרב" refers to a case where there's a majority of one type, and the placement is done according to the majority. This is a common interpretive strategy for such baraitot. However, R' Yehuda then presents a machloket on bilul of tamim and ba'al mum blood, where R' Eliezer does permit placement even in bilul. Ritva explains that this particular machloket of tamim and ba'al mum is unique. Here, R' Eliezer applies ro'in even to bilul because the pesul of ba'al mum blood is lighter; it's still blood that could potentially be kasher in other contexts (e.g., if the animal was mum'd after shechita). This allows R' Eliezer to "view" it as water. The Rabbis, however, view it as intrinsically pasul blood, which cannot be purified by ro'in.

Ritva's detailed exposition brings out the layers of machloket and the conditions under which ro'in is applied or rejected. He meticulously distinguishes between different types of mixtures (bilul vs. kosos) and different categories of pesul (e.g., chatat/olah vs. tamim/ba'al mum), providing a comprehensive framework for understanding the sugya's intricate arguments.

Friction

The sugya presents a classic dialectical tension, where an Amoraic distinction (Rava's) is immediately challenged by a seemingly contradictory baraita. This serves to refine our understanding of machloket Tannaim and the criteria for applying specific halakhic principles.

The Strongest Kushya: Rava's Distinction vs. R' Yehuda's Baraita

The core friction emerges immediately after Rava's attempt to simplify the Mishnaic machloket:

Rava's Chiddush:

אלא אמר רבא לא נחלקו רבי אליעזר ורבנן בנתערב. מתי נחלקו? בתערובת כוסות. Rather, Rava says: Rabbi Eliezer and the Rabbis do not disagree with regard to [actual blood] mixed together. When they disagree it is with regard to cups [of blood] that were intermingled. Zevachim 81a:2-3

Rava's statement asserts a fundamental distinction: the Mishna's dispute (R' Eliezer permits placing mixed chatat/olah blood via ro'in, Rabbis disqualify it) only applies to kosos (intermingled cups where the identity of each is uncertain), not to bilul (actual, homogenous mixing). According to Rava, in bilul, everyone agrees the blood is sacrificed. This would mean that the machloket is not about ro'in per se, but about how to act in a state of safek.

The Kushya from R' Yehuda's Baraita:

והא לא פליגי בנתערב? והתניא ר' יהודה אומר לא נחלקו ר"א וחכמים על דם חטאת שנתערב בדם עולה שיקרב, ועל דם נבעל ומרבע שישפך. על מה נחלקו? על דם תמים שנתערב בדם בעל מום, שר"א אומר יקרב בין בנתערב בין בתערובת כוסות, ורבנן אומרים לא יקרב. And do they not disagree with regard to blood mixed together? But isn't it taught in a baraita: Rabbi Yehuda said: Rabbi Eliezer and the Rabbis did not disagree in a case of blood of a sin offering that was mixed with blood of a burnt offering that the mixture shall be sacrificed, or in a case of blood that was fit for presentation that was mixed with the blood of an animal that copulated with a person, or an animal that was the object of bestiality, that it shall not be sacrificed. With regard to what case did they disagree? With regard to blood of an unblemished animal that was mixed with blood of a blemished animal, as Rabbi Eliezer says that it shall be sacrificed, whether in a case of blood mixed together or in a case of intermingled cups, and the Rabbis say it shall not be sacrificed. Zevachim 81a:7-9

This baraita poses a two-pronged challenge to Rava:

1. First Part: "לא נחלקו ר"א וחכמים על דם חטאת שנתערב בדם עולה שיקרב" – R' Yehuda states that everyone agrees that chatat blood mixed with olah blood shall be sacrificed. This contradicts the Mishna's initial presentation of a machloket between R' Eliezer and Rabbanan on this very case (Zevachim 80b). If Rava's chiddush was meant to resolve the Mishna by saying the machloket is only in kosos, R' Yehuda's baraita now says everyone agrees even in bilul (and implicitly, then, also in kosos if they are the same din) that chatat and olah mixed are kasher. This is problematic for Rava's thesis that the Mishna's machloket is specifically about kosos.
2. Second Part: "על מה נחלקו? על דם תמים שנתערב בדם בעל מום, שר"א אומר יקרב בין בנתערב בין בתערובת כוסות, ורבנן אומרים לא יקרב." – This part explicitly states that the machloket between R' Eliezer and Rabbanan does apply to bilul ("בין בנתערב") in the case of dam tamim (unblemished) mixed with dam ba'al mum (blemished). This directly undermines Rava's central assertion that "לא נחלקו רבי אליעזר ורבנן בנתערב" (they do not disagree in bilul).

The kushya is powerful because the baraita uses the same terminology (bilul and kosos) that Rava employed to distinguish the machloket, yet it presents a machloket in bilul where Rava said there was none, and it seems to imply a unanimous agreement in the case where the Mishna showed a machloket.

The Best Terutz: Aliba d'R' Eliezer and Amoraic Interpretation

The Gemara offers a nuanced terutz to reconcile Rava's position with R' Yehuda's baraita:

ר' יהודה, אליבא דרבי אליעזר, מתני ליה בין בנתערב בין בתערובת כוסות, אבל רבנן מתני ליה בתערובת כוסות. Rabbi Yehuda, in accordance with the opinion of Rabbi Eliezer, teaches that the dispute applies both in a case of blood mixed together and in a case of intermingled cups, but the Rabbis who taught the mishna maintain that Rabbi Eliezer and the Rabbis disagree only in a case of intermingled cups. Zevachim 81a:10-11

This terutz is a classic Amoraic move, distinguishing between Tannaim based on whose interpretation they are presenting.

1. Reconciling the Second Part of the Baraita (Machloket in Bilul): The Gemara asserts that R' Yehuda, when describing R' Eliezer's view, presents R' Eliezer as holding his ro'in principle (and thus the machloket with Rabbanan) applies even to actual mixing (bilul), not just kosos. This means R' Eliezer's principle is broadly applicable.
2. Reconciling Rava's Chiddush (No Machloket in Bilul): Rava's assertion that "לא נחלקו... בנתערב" (they did not disagree in bilul) is understood as applying only to the Rabbis' understanding of the machloket. The Rabbis of our Mishna limit R' Eliezer's ro'in to kosos because they find it too radical for actual bilul. Thus, from the Rabbis' perspective (as presented in our Mishna), the machloket is only about kosos.

Implications of the Terutz:

• Layered Interpretations of Machloket Tannaim: The terutz reveals that Tannaim sometimes describe other Tannaim's opinions not as the latter actually held them, but as they understood or framed them within their own interpretive system. R' Yehuda is presenting R' Eliezer's maximalist view of ro'in, while the Rabbis in our Mishna are presenting a more constrained view of R' Eliezer's opinion, perhaps to emphasize their own disagreement.
• The Scope of Ro'in: Ultimately, the sugya indicates that R' Eliezer's ro'in principle is expansive, applying even to bilul (according to R' Yehuda's understanding of R' Eliezer). The Rabbis, however, reject ro'in in bilul entirely, perhaps seeing it as too great a deviation from the requirement of placing pure blood. They might concede to ro'in only in kosos out of a desire to salvage a korban where the safek is unavoidable, and where the bilul isn't truly homogenous.

Further Elaboration from Rishonim: Rashi (Zevachim 81a s.v. "רבי יהודה אליבא דרבי אליעזר") makes this explicit: R' Yehuda teaches aliba d'R' Eliezer that ro'in applies to bilul as well. The Rabbis of the Mishna, however, when presenting the machloket, restrict R' Eliezer's opinion to kosos, implying that they consider bilul to be pasul even for R' Eliezer. This is a common interpretive struggle in the Gemara: how to reconcile seemingly contradictory statements from Tannaim regarding the views of other Tannaim.

Tosafot (Zevachim 81a s.v. "הג"ה בל תוסיף מהיכא") also addresses this, reinforcing the idea that the Gemara's terutz is a sophisticated way of understanding the differing levels of acceptance or rejection of R' Eliezer's ro'in principle among the Tannaim. The initial baraita of R' Yehuda which states "לא נחלקו... שיקרב" (no dispute... it is sacrificed) for chatat and olah mixed is still challenging. Rashi explains this to mean that if it was placed, it is kasher, but lechatchila it should not be done (Rashi Zevachim 81a s.v. "לא נחלקו ר"א וחכמים"). This suggests a distinction between bedi'eved and lechatchila that further refines the understanding of the machloket.

In essence, the Gemara's terutz is not simply a linguistic trick, but a profound statement on the nature of halakhic discourse, where the presentation of an opinion can itself be subject to machloket and interpretation. It teaches us to look beyond the surface level of a Tanna's statement to understand the underlying framework from which they operate.

Intertext

The sugya on Zevachim 81a is deeply interwoven with various scriptural passages, particularly those relating to sacrificial blood and the principles of kedusha and bitul. The Gemara explicitly cites three different drashot for the fundamental principle that "דם העולים למזבח אינן בטלין זה בזה" (blood that ascends to the altar is not nullified by one another). This intertextual dialogue reveals the rich tapestry of midrash halakha and the nuanced ways in which Tannaim derived foundational halakhot.

1. "והקריבו בני אהרן את הדם וזרקו את הדם" (Vayikra 1:5)

This verse, from the context of an olah offering, is presented by Rava as a source for ein bitul. The Gemara (Zevachim 81a) explains the repetition of "דם" (blood) as teaching that even if the blood of an olah is mixed with other bloods that are also placed below the red line (e.g., todah, shelamim, asham, bechor, ma'aser, pesach), it is still considered "דם" and shall be sprinkled.

• Sifra (Vayikra, Parashat Vayikra, Perek 4:1): The Sifra is the likely Tannaic source for this drasha. It delves into the various categories of blood that could be mixed with olah blood, emphasizing that the repetition of "דם" serves to include all these valid bloods, preventing their nullification. Rashi (Zevachim 81a s.v. "והקריבו וזרקו מה ת"ל דם דם") explains that the verse could have simply said "והקריבו וזרקו אל המזבח" (and they shall present and sprinkle onto the altar). The double mention of "דם" (blood, blood) is therefore superfluous and teaches an expansive halakha. This drasha highlights the inherent kedusha of sacrificial blood, which resists bitul even in mixtures, provided all components are kasher and share a similar avodah location.

2. "ולקח מדם הפר ומדם השעיר" (Vayikra 16:18)

This verse describes the High Priest taking blood from both the bull and the goat on Yom Kippur for the inner avodah. The Gemara (Zevachim 81a) cites this as another source for ein bitul. The implication is that even though the bloods are taken into the same vessel, they retain their distinct identities and properties, not nullifying each other.

• Talmud Yerushalmi (Yoma 5:7 / 44c): The Yerushalmi discusses this verse in the context of the Yom Kippur service, emphasizing that the bloods are distinct even when collected together. The Gemara in our sugya (Zevachim 81a) presents a machloket Tannaim about this drasha. Some Tannaim reject it because they hold "אינו מערב לקרונות" (he does not mix for the corners), meaning the High Priest keeps them separate for the distinct applications. This exemplifies how different Tannaim had differing hermeneutical principles and accepted or rejected specific derashot. The very existence of this machloket about the drasha indicates that the principle of ein bitul b'damim was debated regarding its scriptural source, not necessarily its existence.

3. "קודש הם" (Bamidbar 18:17)

This verse refers to the bechor (firstborn animal), stating "אך בכור שור או בכור כשב או בכור עז לא תפדה קדש הם" (However, the firstborn of an ox, or the firstborn of a sheep, or the firstborn of a goat, you shall not redeem; they are holy). The Gemara (Zevachim 81a) uses the emphatic "הם" (they) to teach that even if bechor blood is mixed with other sacrificial blood, it is sacrificed, meaning it is not nullified.

• Sifrei Bamidbar (Piska 120): This Midrash Halakha is the likely source for this drasha. It typically unpacks the nuances of seemingly superfluous words. The word "הם" (they), when grammatically redundant, often serves to include or exclude additional cases. Here, it includes the mixed blood of a bechor. This drasha focuses on the inherent kedusha of the bechor itself, which extends to its blood and prevents its bitul.
• Cross-reference to Vayikra 27:26: The Gemara (Zevachim 81b) then asks why other Tannaim don't use this source. It answers that they interpret "קודש הם" to mean "הם קרבים, אבל תמורתן אינה קרבה" (they are sacrificed, but their substitute is not sacrificed). This alternative drasha is itself derived by others from "הוא יהיה קודש" (Vayikra 27:26), referring to the bechor and its temura. This showcases the flexibility and multiplicity of drashot: a single phrase can yield different halakhot for different Tannaim, leading to a rich interplay of interpretive traditions. The concept of temura (substitute offering) is itself a profound halakhic principle regarding the transfer of kedusha.

These intertextual references are not mere prooftexts; they are the very fabric of the sugya's reasoning. They illustrate:

• The Depth of Scriptural Exegesis: How precise linguistic analysis (e.g., repetition of words, superfluous pronouns) leads to significant halakhic conclusions.
• The Principle of Ein Bitul B'Damim: The repeated derivations from different verses underscore the centrality and robustness of this principle in Kodashim, even if its precise source is debated.
• Variations in Midrashic Methodologies: The sugya explicitly notes that "האי תנא סבר ליה מהכא והאי תנא סבר ליה מהתם" (this Tanna derives it from here, and that Tanna derives it from there), demonstrating that Tannaim could agree on a halakha while disagreeing on its midrashic source. This intellectual honesty is a hallmark of Talmudic discourse.

The sugya's exploration of these pesukim thus provides insight not only into the halakhot of mixed blood but also into the very process of halakhic derivation from the Torah.

Psak/Practice

The sugya on Zevachim 81a, despite its intricate debates, yields several clear halakhic conclusions, particularly regarding the principle of ro'in and the status of mixed sacrificial blood. The authoritative codifier for Kodashim is Rambam, and his rulings reflect the Gemara's final positions.

1. Rejection of R' Eliezer's Ro'in Principle

The central machloket between R' Eliezer and the Rabbis in the Mishna (Zevachim 80b) concerns whether one "views" improperly placed blood as water (ro'in). R' Eliezer asserts this, allowing for the placement of mixed bloods (e.g., chatat above the line, olah below) by deeming the "extra" blood as water. The Rabbis reject this.

• Psak: The halakha is definitively not according to R' Eliezer. The principle of ro'in is not accepted in halakha for avodah.
• Rambam: "דם חטאת ועולה שנתערבו דמיהן, ישפכו לאמה. ואם זרקן למעלה, פסול; למטה, פסול. שאין דם חטאת עולה למטה, ודם עולה אינו עולה למעלה." (Mishneh Torah, Hilchot Ma'aseh HaKorbanot 5:11). Rambam explicitly states that such a mixture is disqualified and must be poured into the drain, effectively ruling against R' Eliezer's ro'in. The strict adherence to the prescribed locations for blood placement (above or below the red line) is paramount. If one places chatat blood below the line, or olah blood above, it is a pesul (disqualification).

2. The Principle of Ein Bitul B'Damim Ha'Olim L'Mizbeach

A crucial takeaway is the principle that blood eligible for the altar is not nullified when mixed with other such bloods (damim ha'olim l'mizbeach einan mitbatlim zeh ba'zeh). The sugya explores various drashot for this, ultimately affirming the principle itself.

• Psak: If different types of blood, all fit for the altar, are mixed, and their placement locations are the same, they are not nullified and can be sacrificed.
• Rambam: "דם הקרבנות שנתערבו זה בזה, אם היו כולם ראויין להקרבה, הרי הן קרבים." (Mishneh Torah, Hilchot Ma'aseh HaKorbanot 5:10). This is the general rule. He then gives examples: "כיצד? דם עולה שנתערב בדם עולה, או בדם שלמים, או בדם אשם, או בדם תודה, או בדם בכור, או בדם מעשר, או בדם פסח, וכולם ראויין לזריקה למטה, כולם נזרקים למטה." (Ibid.). This covers most scenarios where the avodah (placement location and method) is compatible.
• Meta-Psak Heuristic: This principle establishes a meta-halakha about the enduring kedusha of sacrificial blood. Unlike many other mixtures in halakha where bitul b'rov (nullification by majority) or bitul b'shishim (nullification by 60x) applies, damim ha'olim l'mizbeach are qualitatively different and retain their individual kedusha.

3. Equivalence of Shiyarei Chatat and Dam Olah Locations

The debate between Abaye and Rav Yosef (and parallels from Eretz Yisrael) concerned whether the place of shiyarei chatat (remainder of a sin offering's blood, poured on the yesod) is the same as the place of dam olah (sprinkled below the red line).

• Psak: The halakha generally follows the view that their locations can be considered the same for certain types of chatat.
• Rambam: "דם שיריים של חטאת שנתערב בדם עולה, אם היו שניהם ראויין למקום אחד, כגון שיריים של חטאת החיצונה, ועולה, הרי הן נזרקין למטה." (Mishneh Torah, Hilchot Ma'aseh HaKorbanot 5:12). Rambam clarifies that this applies specifically to shiyarei chatat chitzona (external sin offering), whose remainder is poured on the base of the mizbeach hachitzon. However, shiyarei chatat p'nimit (inner sin offering, whose remainder is poured on the base of the mizbeach hachitzon after inner avodah) mixed with olah blood is pasul: "אבל שיריים של חטאת הפנימית, שנתערבו בדם עולה, ישפכו לאמה." (Ibid.). This nuanced ruling reflects the Gemara's eventual terutz from Rav Yitzchak bar Yosef (Zevachim 81b) that the baraita refers to chatat chitzona mixed with shiyarei chatat p'nimit.

In summary, the sugya provides critical insights into the handling of sacred substances, establishing strict boundaries for avodah while affirming the enduring sanctity of sacrificial blood in appropriate contexts. The rejection of ro'in emphasizes the objective requirements of the mitzvah, while the principle of ein bitul b'damim highlights the unique qualitative kedusha of offerings.

Takeaway

This sugya underscores the rigorous precision demanded in avodat hakorbanot, where even a seemingly minor deviation or mixture can lead to disqualification. It vividly demonstrates the intricate midrashic process through which fundamental halakhic principles, such as the enduring kedusha of sacrificial blood, are painstakingly derived and defended across diverse Tannaic opinions.
