Mishneh Torah, Circumcision 1

On-RampIntermediate – From Familiar to FluentMarch 8, 2026

Hey, partner! Ready to dive into some Rambam? This first chapter of Hilchot Milah is a masterclass in legal precision, but it also throws out some fascinating, non-obvious ideas right from the jump. For instance, have you ever considered why the intense punishment of karet applies to the uncircumcised person himself, but not to a father who, G-d forbid, neglects to circumcise his son? It's a subtle distinction with profound implications.

Context

To really appreciate the Rambam's discussion here, it helps to remember his unique stance on the source of the mitzvah of circumcision. While the covenant of Brit Milah is famously established with Abraham in Genesis 17, the Rambam, in his Commentary on the Mishnah (Chulin 7:6) and elsewhere, posits that our halakhic obligation doesn't stem directly from that original command. Instead, he grounds it in the commandment given to Moses at Sinai (Leviticus 12:3), "On the eighth day, the child's foreskin will be circumcised." This might seem like a technicality, but it's crucial. It means that while Abraham's act is foundational and provides many particulars, the binding legal force for all generations comes through the Sinaitic revelation, integrating milah into the broader framework of Torah law. This approach allows Rambam to rigorously apply halakhic principles, even to a mitzvah as ancient and fundamental as circumcision.

Text Snapshot

Let's zero in on the opening lines:

Circumcision is a positive mitzvah whose lack of fulfillment is punishable by karet, as [Genesis 17:14] states: "And an uncircumcised male who does not circumcise his foreskin - this soul will be cut off from his people."

A father is commanded to circumcise his son... If the father or the master transgressed and did not circumcise them, he negated the fulfillment of a positive commandment. He is not, however, punished by karet, for karet is incurred only by the uncircumcised person himself.

Insight 1: The Layered Structure of Responsibility

The Rambam meticulously lays out a clear hierarchy of responsibility for milah, demonstrating a sophisticated understanding of individual, familial, and communal obligations. It starts with the father, extends to the master for his slaves, then to the court, and finally, to the individual himself upon reaching bar mitzvah. This isn't just a list; it's a cascading system of accountability designed to ensure the mitzvah is ultimately fulfilled. The father is the primary agent, "commanded to circumcise his son" (Halacha 1:1). If he fails, he "negated the fulfillment of a positive commandment" (Halacha 1:2). Notice the specific phrasing: he negated a positive commandment, but karet does not apply to him.

This distinction is critical and leads to the next layer: the court. The Rambam states, "The court is obligated to circumcise that son or slave at the proper time and should not leave an uncircumcised male among the Jewish people or their slaves" (Halacha 1:2). This isn't just permission; it's an obligation. The court must act, even "against [the father's] will" (Halacha 1:2). This shows a communal imperative that overrides individual parental autonomy when the mitzvah is neglected. As Yitzchak Yeranen on Halacha 1:1:3 notes, the Rambam doesn't say the court is liable for karet if they fail, because responsibility can be diffused among many, unlike the singular liability of the uncircumcised person. The very fact that the court must step in underscores milah's status as a foundational covenantal sign for the entire Jewish people, not just a private family matter.

Finally, if all else fails, "when [the child] reaches bar mitzvah, he is obligated to circumcise himself" (Halacha 1:3). This completes the chain, indicating that the mitzvah ultimately rests with the individual if others have not fulfilled it on his behalf. Tzafnat Pa'neach (1:1:3) highlights this by explaining that there are three aspects to the mitzvah: to remove the foreskin (a single deed), to be circumcised, and not to be uncircumcised (ongoing qualities). This ongoing nature means that the individual's obligation is not a secondary, delayed mitzvah, but the very same continuous state of being circumcised.

Insight 2: The Nuance of Karet

The term karet (כרת), usually translated as "cutting off," is one of the most severe punishments in the Torah. Footnote 3 clarifies its dual meaning: "Premature death at the hand of God... and a severe spiritual punishment, the 'soul's being cut off,' and not being granted a share in the world to come." What's striking here is the Rambam's precise application of karet. He explicitly states that it is "incurred only by the uncircumcised person himself" (Halacha 1:1). The father, master, or court who fails to perform the mitzvah merely "negated the fulfillment of a positive commandment" (Halacha 1:2). This is a significant distinction. The one responsible for performing the act is not subject to the same existential consequence as the one who bears the mark (or lack thereof) of the covenant.

This leads to an interesting debate among commentators regarding an adult who delays his own circumcision. The Rambam states that the adult "is not, however, liable for karet until he dies uncircumcised" (Halacha 1:3, footnote 7). This implies a continuous window of opportunity for repentance and fulfillment. The Kessef Mishneh explains that until death, it's not truly known if he will perform the mitzvah. However, the Ra'avad objects, arguing that "each day he does not perform the mitzvah, he is liable for karet and is worthy of premature death." This highlights a fundamental tension: Is karet triggered by the act of omission at a specific point, or only by the final state of being uncircumcised at the end of one's life? Rambam leans towards the latter, emphasizing the enduring possibility of fulfilling the covenant.

Insight 3: The Imperative of Communal Intervention

While the father has the initial and primary mitzvah to circumcise his son, the Rambam's text quickly introduces a powerful communal safeguard: "The court is obligated to circumcise that son or slave at the proper time... We may not circumcise a person's son without his knowledge, unless he has transgressed and did not circumcise him. [In such an instance,] the court must circumcise [the child] against [the father's] will" (Halacha 1:2).

This creates a fascinating tension. Normally, Jewish law emphasizes individual responsibility and avoiding "stealing a mitzvah" from another, a concept the Rambam himself addresses elsewhere (Hilchot Chovel UMazik 7:13-14). Yitzchak Yeranen on 1:1:1 delves into this, discussing the halakha of someone performing a mitzvah that another was supposed to do. He clarifies that if the father intended to do it and someone else "stole" it, there could be liability. But in the case of outright transgression by the father, the court's obligation takes precedence. The communal imperative to ensure a Jew is circumcised is so strong that it overrides the normal respect for a father's autonomy and even his refusal. The very identity of the child as part of the Jewish people is at stake. The Yitzchak Yeranen further explains that if the father neglected the mitzvah, the court's action is not "stealing" but fulfilling a necessary communal duty. This is not merely a permissive action but a required one, reflecting the profound significance of milah as the mark of the covenant for the entire nation.

Two Angles

The Father's Ongoing Obligation: A Debate

The Rambam states, "A father is commanded to circumcise his son" (Halacha 1:1). A crucial question arises: Is this command limited strictly to the eighth day, or does it continue if the eighth day passes without the brit being performed?

The Nachal Eitan (on 1:1:1) addresses this directly, asserting that the Rambam's unqualified statement implies the father's obligation continues even after the eighth day. He buttresses this view by citing Rashi and Tosafot, who agree that "if its time has passed, milah is not nullified," meaning the very same mitzvah that was due on the eighth day is still fulfilled on the ninth or later. The Nachal Eitan even draws a parallel to the omer offering, where despite the possibility of cutting it before Shabbat, it still overrides Shabbat when performed "in its time." This perspective emphasizes the enduring nature of the father's personal mitzvah until the circumcision is done.

However, the Nachal Eitan also references an opposing view, found in the Yad HaMelekh, which contends that the father's mitzvah applies only on the eighth day. According to this view, once that specific day passes, the father's direct personal obligation for that particular mitzvah is relinquished or transferred, perhaps to the beit din or the child himself upon maturity. The Yad HaMelekh's argument, as cited, questions why milah on the eighth day would override Shabbat if the father could simply wait until after Shabbat to fulfill his obligation. The Nachal Eitan vigorously refutes this, emphasizing that performing a mitzvah "in its time" is a value in itself, overriding Shabbat, even if the mitzvah could still be performed later. This debate highlights whether the father's role is a one-time temporal duty or an ongoing responsibility until the child enters the covenant.

Practice Implication

This chapter, particularly Halachot 16-18, profoundly shapes daily Jewish practice by prioritizing life (Pikuach Nefesh) over the exact timing of the mitzvah of Brit Milah. The Rambam explicitly states, "A sick person should not be circumcised until he regains his health. Seven full days should be counted from the time he regains his health until he is circumcised" (Halacha 1:16). He extends this to specific conditions like jaundice ("very yellowish complexion") or excessive redness, requiring delay until the child's blood recovers and complexion normalizes (Halacha 1:17). Most critically, he concludes, "We should not circumcise a child who is afflicted with any sickness at all, since the danger to life takes precedence over everything. Circumcision can be performed at a later date, while it is impossible to bring a single Jewish soul back to life" (Halacha 1:18).

This is not a mere suggestion but a foundational principle. In contemporary practice, this means that medical considerations always take precedence. If a baby is born prematurely, has jaundice, or any other health concern, the brit is delayed. The eighth-day mitzvah is postponed until a doctor certifies that the baby is healthy enough for the procedure, and often, an additional waiting period is observed. This isn't viewed as a "lesser" brit but as the correct way to perform the mitzvah under those circumstances, as the Torah itself values life above all.

Chevruta Mini

  1. The Rambam outlines a chain of responsibility: father, then court, then the adult child. If a father actively refuses to circumcise his son, and the court steps in, does the father still "negate a positive commandment," or is his sin alleviated by the court's action? What are the tradeoffs in defining the father's ongoing culpability?
  2. The mitzvah of milah on the eighth day overrides Shabbat. However, the Rambam lists several conditions (e.g., jaundice, Caesarean birth, being born during beyn hash'mashot) where the brit is delayed until Sunday, even if the eighth day falls on Shabbat. What are the underlying values or halakhic principles that lead to overriding Shabbat in some cases, but delaying the brit in others, especially when the delay itself might mean postponing a mitzvah that could have been done on Shabbat?

Takeaway

The Rambam meticulously crafts the laws of Brit Milah as a multi-layered covenantal imperative, prioritizing individual obligation, communal responsibility, and above all, the sanctity of life.
