Jerusalem Talmud Nazir 3:5:7-7:2

Deep-DiveIntermediate – From Familiar to FluentDecember 19, 2025

Hey, great to dive into this Yerushalmi Nazir passage together! What strikes me as particularly non-obvious here, right off the bat, is the radical tension between the intention to undertake a sacred vow like nezirut and the halakhic impossibility of fulfilling its core tenets when you're already in a state of ritual impurity. Can a vow truly "take effect" if, by its very nature, you're instantly violating its most stringent prohibition? It forces us to reconsider the fundamental mechanics of neder (vow) and tum'ah (impurity) in a way that’s far more intricate than simple cause-and-effect.

Context

To truly appreciate the nuances of this passage, we need a quick refresher on the concept of nezirut and the unique severity of tum'at met (impurity of the dead). A nazir (Nazarite) undertakes a special vow, detailed in Numbers Chapter 6, to dedicate themselves to God for a specified period. This involves three primary prohibitions: refraining from grape products (wine, grapes, etc.), not cutting their hair, and avoiding all contact with the dead, including entering a cemetery or being under the same roof as a corpse. The nazir's commitment to purity from the dead is so profound that even contact with close relatives (parents, siblings, spouse) is forbidden, overriding the general mitzvah for others to attend to their deceased kin. If a nazir becomes impure from the dead during their term, all the "earlier days fall away" (Numbers 6:12), requiring them to restart their count, bring specific sacrifices, and undergo a purification process.

Now, tum'at met itself is the most severe form of ritual impurity in Jewish law. It renders a person or object unfit to enter the Temple or partake in sacred offerings. Crucially, it's not merely a physical state but a spiritual one, requiring a seven-day purification process culminating in immersion in a mikvah (ritual bath) and, specifically for tum'at met, sprinkling with the ashes of the Red Heifer on the third and seventh days. A cemetery is, by definition, a place saturated with tum'at met, transmitting impurity to anyone within its bounds, often through ohel (tent/canopy) even without direct contact.

So, when our Mishnah opens with someone vowing nezir while in a cemetery, it immediately sets up a paradox. The person is committing to a state of extreme purity while simultaneously being in the most extreme state of impurity, in a place explicitly forbidden to a nazir. This isn't just a minor infraction; it's a direct contradiction to the very essence of the vow's stringent purity requirements. This situation forces the Talmud to grapple with foundational questions about the nature of vows, the mechanics of impurity, and the conditions under which halakha can be practically applied. Does the vow take effect immediately, even if it means an instant violation? Or is it suspended until the conditions for its proper observance can be met? The answers to these questions reveal deep insights into the Rabbinic understanding of intent, obligation, and the interface between human action and divine law.

Text Snapshot

Here’s a snapshot of the core text we're exploring today:

MISHNAH: If somebody made a vow of nazir while he was in a cemetery, even if he stayed there for thirty days, they are not counted and he does not bring a sacrifice for impurity. If he left and re-entered, they are counted and he has to bring a sacrifice for impurity. Rebbi Eliezer said, not on that day, since it is said: “The earlier days fall away,” until he has earlier days. Jerusalem Talmud Nazir 3:5:7-7:2

Insight 1: The Paradox of Vowing in Impurity – Immediate Effect vs. Practical Inability

The Mishnah opens with a seemingly straightforward ruling: "If somebody made a vow of nazir while he was in a cemetery... they are not counted and he does not bring a sacrifice for impurity." This statement, on its surface, suggests that the vow, while perhaps technically "made," doesn't function in the usual way. The days spent in the cemetery don't count towards the nezirut term, and no sacrifice for impurity is required. But why?

The Gemara immediately dives into this, and the underlying tension is profound: Does the neder (vow) of nezirut take effect the moment it's uttered, even if the individual is in an impossible state to fulfill it? Or is it somehow suspended or rendered inoperative until the conditions for proper observance are met?

Rebbi Johanan argues for immediate efficacy and ongoing liability, stating: "one warns him about everything for every possible leaving, and he is whipped." His view is that the vow does take effect the moment it is uttered. From that instant, the person is a nazir, and thus obligated to leave the cemetery. Each moment or interval of remaining in the cemetery, after being warned, constitutes a separate violation, potentially incurring lashes. This is a powerful assertion of the vow's binding nature: even if you start in a state of sin, the neder still binds you, and you immediately become liable for further transgressions. The footnotes clarify that R. Johanan understands the biblical prohibition "he shall not come" (Numbers 6:6) as a general prohibition against being near the dead, distinct from "he may not defile himself" (Numbers 6:7), which refers to actively contracting impurity. Thus, even if already impure, the nazir is still forbidden from being there.

Rebbi Eleazar, however, offers a contrasting perspective: "he does not accept [warning] unless he leaves and returns." For R. Eleazar, the vow's practical effectiveness, particularly regarding punishment and the counting of days, is suspended until the nazir leaves the cemetery and then re-enters. His view suggests that the initial act of vowing in impurity creates a state where the nezirut is latent, not fully active in terms of its punitive consequences, until a moment of potential purity (leaving the cemetery) is then violated by re-entry. This implies a deeper principle: for a neder to fully "kick in" with all its liabilities, there must be a genuine opportunity to observe it, or at least a moment of choice to transgress after an initial attempt at observance.

The subsequent debate between Rebbi Tarphon and Rebbi Akiva further illuminates this tension when discussing the case of "If he left and re-entered." Rebbi Tarphon "frees him from prosecution," asking, "what did this one add to his desecration?" His argument is rooted in the idea that since the person was already impure when he made the vow, re-entering doesn't add to his state of impurity in a way that warrants new prosecution or a sacrifice. He's already "maximally" impure from the cemetery. This perspective emphasizes the initial state of impurity as a mitigating factor against further liability for the same type of impurity.

Rebbi Akiva, ever the master of nuanced distinctions, "declares him guilty." He argues, "as long as he was there, he was defiling himself by the impurity of seven days. When he left, he was defiling himself by the impurity of evening. When he re-entered, defiling himself by the impurity of (evening) [scribal error, should be '7 days']." R. Akiva's brilliance lies in distinguishing between types or degrees of impurity. While in the cemetery, the nazir is in a state of tum'at met (seven-day impurity), which can transmit further seven-day impurity. Upon leaving, even if still ritually impure, his capacity to transmit impurity might change to a lesser form (impurity of evening, tamei yom) if he's no longer in direct contact with the source. Re-entering the cemetery, however, reinstates the more severe tum'at met transmission. Therefore, from R. Akiva's perspective, the nazir did "add to his desecration" by changing his impurity status and then re-acquiring the more stringent form. This isn't just about being impure or not; it's about the specific halakhic category of impurity. This highlights a fundamental principle: halakha often operates on precise classifications and distinctions, even within seemingly similar states. A nazir in a cemetery is not just "impure"; they are impure in a specific way with particular implications, and changing that way (even if still impure) can trigger new obligations.

This section, therefore, doesn't just give a ruling; it unpacks the intricate relationship between the legal force of a vow, the state of the individual, and the precise definitions of ritual impurity. It demonstrates how Amoraic masters could dissect a simple Mishnah into profound philosophical and legal debates about intent, status, and the very nature of obligation.

Insight 2: The Mechanism of Warning (התראה) and Liability

The concept of hatra'ah (warning) is a cornerstone of Jewish criminal law, and its intricate application to the nazir in the cemetery is a central theme in this passage. For a person to be liable for lashes (malkot) for violating a Torah prohibition, they generally must have been warned immediately prior to the transgression by two witnesses, who must also specify the punishment for the act. This ensures that the transgression is intentional and done with full knowledge of its prohibited nature and consequences.

The Gemara immediately applies this concept to our nazir who vowed in the cemetery. Rebbi Johanan states, "one warns him about wine and shaving." This implies that even while impure, the vow is active enough to make the nazir liable for other nezirut prohibitions like drinking wine or shaving, and thus can be warned about them. The footnote explains this means the vow is valid immediately, and the nazir can be punished for other infringements.

Rebbi Simeon ben Laqish (Reish Lakish) disagrees sharply: "since one cannot warn him because of impurity, one does not warn him about wine and shaving." Reish Lakish's reasoning is that if the nazir cannot be warned about the primary violation (impurity from the dead), then the entire vow is suspended regarding warnings and punishments for any of its prohibitions. His view suggests a holistic understanding of nezirut: if a nazir is in a state where they cannot observe a core tenet (purity), then the entire structure of warnings and punishments for nezirut is temporarily invalid. The vow is "on hold" until purification. This highlights a key debate: Is nezirut a collection of independent prohibitions, or an indivisible whole where a fundamental breach or inability to comply affects the entire status?

The Gemara then challenges R. Johanan, noting an apparent contradiction in his own statements across different halakhot. "The argument of Rebbi Johanan seems inverted. There [Jerusalem Talmud Nazir 6:4:2], he says, one warns him about wine, impurity, and shaving. And here, he says so?" This is typical Talmudic dialectic: scrutinizing a Sage's consistency across various contexts. The "rabbis from Caesarea" resolve this by suggesting that R. Johanan's view is consistent: he believes that all aspects of the vow become active immediately, including the prohibition of impurity, and thus one can warn him about impurity from the outset. If he can be warned about impurity, then he can certainly be warned about wine and shaving. The core disagreement between R. Johanan and Reish Lakish, therefore, centers on whether the vow's activation is immediate and comprehensive, or if it's contingent on the ability to achieve ritual purity.

Further on, the Gemara delves into the quantity of warnings and punishments. A Mishnah from Nazir 6:4:1 states: "A nazir who drank wine the entire day is guilty only once." This seems to contradict R. Johanan's position that "one warns him about everything for every possible leaving, and he is whipped," implying multiple warnings and lashes for continuous transgression. R. Johanan resolves this by explaining the Mishnah refers to a specific scenario: "that his throat was never empty." If the nazir drank continuously without a break, there was only one opportunity for a warning. However, if there were discrete intervals, even brief ones, between sips, then each interval could constitute a new opportunity for a warning, leading to multiple liabilities. This underscores the precision of halakha regarding hatra'ah: it's not just about the act, but the opportunity to desist after being warned, which defines separate transgressions.

Similarly, the Mishnah states: "If he was defiling himself for the dead the entire day, he is guilty only once." R. Johanan again offers a nuanced explanation: "about one who waits before every leaving, who is whipped." This means if the nazir lingered, left, and re-entered, or waited for an interval equivalent to k'dei hash'tahavah (the time it takes to prostrate oneself, as cited in footnote 68 regarding the Temple), each interval or re-entry could be a new transgression following a warning. This demonstrates that continuous action might be one sin, but discrete, re-initiated actions, particularly after warnings, can be multiple.

The discussion of hatra'ah here is not merely an academic exercise; it has profound implications for how halakha defines criminal responsibility. It grapples with questions of intent, opportunity, and the very nature of an ongoing transgression. Is a continuous state of impurity one long sin or a series of discrete, punishable acts? The answer often hinges on the presence and efficacy of hatra'ah, which forces a person to confront their actions with full knowledge of their prohibited status.

Insight 3: The Intricacies of Counting Days and Sacrifice for Impurity

The Mishnah's statement that if one vows in a cemetery, "they are not counted and he does not bring a sacrifice for impurity," sets the stage for a detailed exploration of what constitutes a "valid day" of nezirut and when the specific sacrifices for impurity are triggered. This isn't just about being impure; it's about the type of impurity and its impact on the nazir's unique status.

The Penei Moshe (on JT Nazir 3:5:1:2) clarifies the Mishnah's point about not bringing a sacrifice: "דכי כתיב קרבן טומאה בנזיר טהור שנטמא הוא דכתיב" – "for when the sacrifice for impurity is written, it is written for a pure nazir who became impure." This is a crucial distinction. The biblical text Numbers 6:10-11 describes the purification process and sacrifice for a nazir who becomes impure during their term. But what about someone who starts their nezirut already impure? According to this interpretation, they don't fit the category of a "pure nazir who became impure," and therefore, the specific sacrifice for impurity from the dead does not apply to them. This doesn't mean they are exempt from all consequences; Penei Moshe adds, "ומ"מ אם התרו בו חייב מלקות" – "nevertheless, if he was warned, he is liable for lashes," reinforcing the idea that while the sacrifice is tied to a specific ritual context (a pure nazir becoming impure), the prohibition itself is still active, incurring lashes if violated intentionally after a warning.

The Mishnah then states, "If he left and re-entered, they are counted and he has to bring a sacrifice for impurity." This scenario is significantly different. The Penei Moshe (on JT Nazir 3:5:1:3) explains this complex process: "יצא מבית הקברות והזה ג' וז' וטבל וטהר מטומאתו והתחיל למנות ימי נזירותו אע"פ שחזר ונכנס אח"כ לבית הקברות עולין לו מן המנין אלו ימים שמנה אחר שטהר הואיל והפסיקה טהרה בין הימים הראשונים שנזר והוא בבית הקברות ובין אלו הימים האחרונים" – "He left the cemetery, was sprinkled on the 3rd and 7th day, immersed, and became pure from his impurity. He then began to count his days of nezirut. Even if he later re-entered the cemetery, these days that he counted after he became pure do count towards his term, since purity intervened between the initial days when he vowed in the cemetery and these later days." This is a critical clarification. The "leaving" isn't just physical removal; it implies a full purification process. Once he is ritually pure and starts counting his nezirut days, he is now considered a "pure nazir." If then he re-enters the cemetery and becomes impure, he does fit the biblical category of a "pure nazir who became impure," and thus must bring the sacrifice and restart his count. This demonstrates that the halakhic status of the nazir (pure vs. impure at the start) profoundly impacts the subsequent obligations, particularly regarding sacrifices.

Rebbi Eliezer’s view further refines the concept of "counting days" and sacrifice: "Rebbi Eliezer said, not on that day, since it is said: 'The earlier days fall away,' until he has earlier days." Penei Moshe (on JT Nazir 3:5:1:4) unpacks this: "כלומר אם בו ביום שטבל וטהר בו ביום נטמא באחת מן הטומאות שהנזיר מגלח אינו סותר אותו היום דכתיב והימים הראשונים יפלו אין הטומאה סותרת עד שיהיו לו ב' ימים של נזירות מנויין" – "Meaning, if on the very day that he immersed and became pure, he became impure again with one of the impurities for which a nazir shaves, that day does not 'fall away,' for it is written 'the earlier days fall away' – impurity does not cause days to fall away until he has two counted days of nezirut." R. Eliezer interprets the plural "days" (ימים) in "earlier days fall away" (Numbers 6:12) to mean at least two days. If a nazir becomes impure on the very first day of their nezirut (after having been pure and started counting), there aren't yet "earlier days" in the plural sense to "fall away." Therefore, that first day isn't invalidated, and no sacrifice is brought. This reveals an extreme precision in biblical exegesis, where a plural form can have direct legal ramifications, affecting the timing and imposition of sacrifices and the invalidation of days.

The discussion then moves to complex scenarios involving combining days of nezirut for a father and his newborn son, and the question of how R. Eliezer’s rule applies. This further highlights the meticulous calculations required in nezirut law, where every fraction of a day and every change in status can affect the ultimate halakha. The core principle remains: the counting of days and the obligation for sacrifices are not automatic; they are governed by specific textual interpretations and the precise halakhic status of the nazir at each moment. This section is a masterclass in how biblical phrases are dissected and applied to create a complex yet coherent legal system.

Two Angles

This passage presents a fascinating opportunity to contrast the interpretive approach of the Yerushalmi commentaries, such as Penei Moshe and Korban HaEdah, with the codificatory methodology of the Mishneh Torah by Maimonides (Rambam). While the former meticulously explain the flow and internal debates of the Talmudic text, the latter synthesizes these discussions into definitive halakhic rulings.

Penei Moshe and Korban HaEdah: Unpacking the Yerushalmi's Internal Logic

Penei Moshe and Korban HaEdah serve as essential guides for navigating the often terse and elliptical style of the Jerusalem Talmud. Their primary goal is to clarify the Yerushalmi's arguments, identify the underlying assumptions of the Amoraim, and reconcile apparent contradictions within the text. They operate within the Yerushalmi's framework, explaining why a particular debate exists and how different opinions are sustained.

For instance, regarding the Mishnah's initial ruling, "If somebody made a vow of nazir while he was in a cemetery... he does not bring a sacrifice for impurity," Penei Moshe (JT Nazir 3:5:1:2) offers a direct textual explanation: "דכי כתיב קרבן טומאה בנזיר טהור שנטמא הוא דכתיב" – "for when the sacrifice for impurity is written, it is written for a pure nazir who became impure." This is a classic interpretive move: grounding the Mishnah's ruling directly in the biblical text (Numbers 6:10-11) by defining the specific scope of the commandment. It explains why the sacrifice doesn't apply by highlighting the legal category the nazir in the cemetery falls outside of. Korban HaEdah (JT Nazir 3:5:1:1) echoes this, stating, "דכי כתיב קרבן טומחה בנזיר טהור שנטמא" – "for when the sacrifice for impurity is written, it is written for a pure nazir who became impure." Both commentaries share this fundamental understanding, emphasizing the importance of the nazir's initial state of purity (or lack thereof) in determining subsequent sacrificial obligations. They are not merely stating the law; they are explaining the reasoning behind the Mishnah's formulation, linking it explicitly to the scriptural source.

Furthermore, when the Mishnah states, "If he left and re-entered, they are counted and he has to bring a sacrifice for impurity," Penei Moshe delves into the necessary steps implied by "left." He clarifies (JT Nazir 3:5:1:3) that "יצא מבית הקברות והזה ג' וז' וטבל וטהר מטומאתו והתחיל למנות ימי נזירותו" – "He left the cemetery, was sprinkled on the 3rd and 7th day, immersed, and became pure from his impurity, and began to count his days of nezirut." This detailed explanation fills in the gaps of the Mishnah's terse language, providing the complete ritual sequence that transforms the nazir from an initial state of impurity into a "pure nazir." Only after this full purification and the start of counting days does a subsequent re-entry into the cemetery trigger the sacrifice. The commentaries are elucidating the process and the conditions that change the nazir's halakhic status, thereby explaining the Mishnah's seemingly contradictory rulings in the two cases. They are teaching us how to read the Yerushalmi, revealing the implicit steps and reasoning that underlie its statements.

Mishneh Torah (Rambam): Codifying the Final Halakha

Maimonides' Mishneh Torah, by contrast, is not primarily an interpretive commentary on the Talmud. Instead, it aims to present a clear, organized, and definitive code of Jewish law. Rambam synthesizes the various Talmudic debates, often selecting one opinion as normative (halakha l'ma'aseh) or offering a nuanced ruling that incorporates elements from different views. His focus is on the practical outcome and the precise legal status.

In Nazariteship 6:8, Rambam directly addresses our Mishnah's scenario: "When a person takes a nazirite vow in a cemetery, the nazirite vow takes effect." This is a crucial starting point. Unlike the Yerushalmi commentaries that might dwell on the nuances of whether the vow is "suspended" or "active" in terms of warnings, Rambam cuts to the chase: the vow is binding. However, he immediately qualifies this: "Even if he remains there for several days, they are not counted for him. He is liable for lashes for remaining there." This aligns with the understanding that the vow is active, and hence prohibitions are in force, but the days spent in impurity don't accrue towards the nezirut term. The liability for lashes (for remaining in the cemetery after warning) reflects R. Johanan's view that the prohibition against being in the cemetery is distinct and actionable, even if one is already impure. The Kessef Mishneh and Radbaz, cited in footnote 23 of the Sefaria text, grapple with Rambam's wording about "warning not to take a nazirite vow," suggesting possible textual emendations to clarify that the warning is for remaining in the cemetery, which is consistent with the Yerushalmi's debates on hatra'ah.

Rambam continues: "If while in the cemetery he contracted impurity in one of the ways which would require a nazirite to shave... he should neither shave nor bring a sacrifice [associated with emerging from] impurity." This directly reflects the Mishnah's ruling and Penei Moshe's explanation: the specific sacrifice for impurity applies only to a pure nazir who becomes impure. A nazir who starts in impurity, even if they contract additional types of impurity while in the cemetery, does not fit this category. Rambam's concise formulation distills the core legal principle without needing to trace the exegetical path back to Numbers 6.

The contrast between these approaches is stark. Penei Moshe and Korban HaEdah provide the "how" and "why" of the Yerushalmi's dialectic, showing how the Rabbis derive and debate the law from scriptural and logical principles. Rambam provides the "what" – the final, authoritative halakha for practice. While the Yerushalmi commentaries invite the learner into the intricate process of Talmudic reasoning, Rambam offers a clear roadmap for observance. Both are indispensable, but they serve different, complementary functions in the study and application of Jewish law.

Practice Implication

The intricate debates in this passage, particularly around when a nazir vow takes effect, the distinction between different types of impurity, and the role of "warning" (hatra'ah) for liability, have profound implications for how we understand personal responsibility, the nature of vows, and the mechanics of halakhic obligation in daily life. Consider a contemporary scenario:

Imagine a person, let's call him David, who is deeply moved by a spiritual experience and, in a moment of intense feeling, declares, "I vow to be a nazir for thirty days!" However, David made this declaration while inadvertently standing on what he later discovers is an unmarked burial plot in an ancient field – a place that halakhically constitutes a cemetery and transmits tum'at met. He was unaware of this at the time.

According to the Mishnah, if David made the vow while impure in this "cemetery," his days spent there "are not counted and he does not bring a sacrifice for impurity." This means his 30-day count for nezirut hasn't truly begun, and if he remains there, he won't be obligated in the specific korban tum'ah. However, the debate between R. Johanan and R. Eleazar, and subsequently R. Tarphon and R. Akiva, becomes critical here.

If David, after learning about the unmarked grave, remains there for a period, does he incur lashes? R. Johanan would argue that the vow took effect immediately, even in impurity. Therefore, he is immediately obligated to leave. If he is warned by two witnesses, "David, you are a nazir, and you are forbidden to remain in this place of impurity! If you stay, you will receive lashes!" and he tarries for a time equivalent to k'dei hash'tahavah (time to prostrate oneself), he would be liable for lashes. Each subsequent warning and lingering could incur further lashes. This reflects a strict view of neder activation and ongoing liability.

However, R. Eleazar might argue that he only "accepts warning" (becomes liable for punishment) "unless he leaves and returns." This implies that the initial vow made in impurity doesn't immediately trigger criminal liability for remaining. David would first need to leave, purify himself, and only then would his nezirut fully activate in a way that makes re-entry a punishable offense.

Now, let's say David does leave the unmarked grave, undergoes the full purification process (which would involve sprinkling on the 3rd and 7th day and immersion, assuming the ashes of the Red Heifer were available, or at least a mikvah and awaiting sunset for taharat yom if the impurity was less severe or he was simply a tamei met not needing Red Heifer ashes for full purification as a nazir), and begins counting his 30 days of nezirut. If, on day 5 of his now-pure nezirut, he accidentally re-enters an unknown cemetery or comes into contact with a corpse, he would then fall under the category of a "pure nazir who became impure." In this case, according to the Mishnah and R. Akiva, he would invalidate his prior days, need to restart his count, and be obligated to bring the korban tum'ah.

This scenario underscores several practical implications:

  1. Immediate Status of Vows: A vow, even if made in a compromised state, can be halakhically binding, creating an immediate obligation to rectify the situation. It's not simply voided.
  2. Nuance of Impurity: Not all impurity is the same. The halakhic status of a person (e.g., pure nazir vs. impure nazir at the outset) profoundly affects their obligations and potential liabilities.
  3. Role of Warning: For many prohibitions, hatra'ah is a prerequisite for criminal punishment. This highlights the importance of clearly informing individuals of their halakhic obligations and the consequences of transgression, ensuring that actions are truly intentional violations.

For David, this means that even if his initial vow didn't immediately lead to counting days or a sacrifice, he was immediately obligated to remove himself from the source of impurity. His continued presence, if warned, could incur severe penalties. And once he became pure, his nezirut was fully active, making him subject to all its stringent rules and sacrifices for future impurity. The passage teaches us that halakha is not just about abstract rules, but about the dynamic interplay between human intent, ritual status, and the precise conditions for culpability and purification.

Chevruta Mini

  1. The Gemara debates whether a nazir who vows in a cemetery is immediately liable for lashes for remaining there (R. Johanan) or only after leaving and re-entering (R. Eleazar). What are the tradeoffs between prioritizing the immediate activation of a vow, even if the person is already in violation, versus suspending full liability until the nazir has a genuine opportunity to observe the vow in purity?
  2. The debate between R. Tarphon and R. Akiva on whether re-entering a cemetery "adds to his desecration" hinges on distinguishing between different types or degrees of impurity. How does this kind of precise halakhic categorization, even within a seemingly uniform state like "impurity," reflect a tension between simple, intuitive understanding and the rigorous demands of legal exactitude?

Takeaway

The initial act of vowing nazir in a cemetery reveals the profound halakhic tension between a vow's immediate binding power and the complex, nuanced conditions required for its proper observance and the imposition of its full liabilities.
