ויקרא, פרק י״ב, פסוק ג׳

Following the laws detailing a mother's ritual impurity after childbirth, the Biblical narrative introduces the commandment of circumcision. Although this instruction was already given to Abraham in the Book of Genesis, it is repeated here after the giving of the Torah to establish new legal precedents. Primarily, this repetition teaches that circumcision performed at its proper time overrides the restrictions of the Sabbath. Without this renewed mandate, one might assume that the prohibition against desecrating the Sabbath—a severe offense punishable by death—would take precedence over circumcision, especially since the Patriarchs observed the rite long before the strict laws of the Sabbath were introduced [אור החיים, רלב״ג, ברטנורא, רד״צ הופמן]. Furthermore, the placement of this commandment establishes a direct chronological link between the conclusion of the mother’s seven-day period of impurity and the day the procedure is performed [אור החיים, רד״צ הופמן].

Commentators offer three primary approaches to explain why the procedure is specifically scheduled for the eighth day. From a physical perspective, a newborn is initially weak and requires time to build the physical stamina necessary to safely undergo the procedure [אור החיים, חתם סופר, תורה תמימה, אם למקרא]. Additionally, during pregnancy, the infant is nourished by blood in the womb; it takes a full seven days for this blood to be completely digested and cleansed from the system, rendering the child pure and fit to enter the holy covenant on the eighth day [ספורנו, שד״ל]. From a familial and social standpoint, the mother remains in a state of ritual impurity for the first seven days following the birth of a male, during which the parents are physically separated and in a state of sadness. Scheduling the event for the eighth day ensures that the mother has already immersed and become pure, allowing both parents to rejoice together at the celebratory feast [שד״ל, חזקוני, בכור שור, הדר זקנים, תורה תמימה]. Spiritually, the child must live through at least one Sabbath before entering the covenant. The Sabbath imparts a vital spiritual soul and fortifies the child's inner strength, a concept mirrored in the law that an animal sacrifice is only acceptable to God from its eighth day of life onward [אור החיים, הדר זקנים, רש״ר הירש].

The specific phrasing of the commandment establishes several foundational laws. The procedure must take place exclusively during the daylight hours, never at night [אבן עזרא, תורה תמימה, מלבי״ם]. Even if the event is delayed for various reasons—such as being postponed to the ninth, tenth, or any subsequent day—it remains strictly limited to the daytime [תורה תמימה, מלבי״ם, חזקוני, אדרת אליהו]. Furthermore, the passive formulation of the command indicates that the obligation to ensure the procedure is performed rests first and foremost upon the father, rather than the mother [תורה תמימה, אבן עזרא, רד״צ הופמן]. A slight variation in the standard sentence structure also reveals a unique legal exception: if a mark of leprosy is present on the foreskin, the obligation to circumcise completely overrides the strict prohibition against cutting away a leprous blemish [תורה תמימה, מלבי״ם, רש״ר הירש, אדרת אליהו]. However, the act only supersedes Sabbath restrictions when dealing with a definitive foreskin. It does not override the Sabbath in doubtful situations, such as a birth occurring exactly at twilight, a child with ambiguous physical traits, or a baby born already circumcised who merely requires a symbolic drop of blood to be drawn [תורה תמימה, חזקוני, אדרת אליהו].

Beyond its legal parameters, the act carries profound philosophical and symbolic depth. A famous dialogue between Turnus Rufus and Rabbi Akiva addresses a fundamental question: if God desires circumcision, why is a child not born already circumcised? Rabbi Akiva explains that the Commandments were given to the Israelites precisely to refine and elevate them. Just as raw wheat requires human processing to be transformed into bread, human beings are tasked with perfecting and repairing their own bodies. The removal of the foreskin symbolizes stripping away the evil and impurity that attached to humanity following the sin of the first man, ultimately purifying the soul [אור החיים, רבנו בחיי, צאינה וראינה]. Symbolically, the phrasing hints at the three distinct physical steps of the procedure: the initial cut, the uncovering of the flesh, and the drawing out of the impure blood [אור החיים]. Ultimately, this physical act reflects a deeper spiritual reality, demonstrating that the inner essence of a Jewish person is already pure and circumcised in heart. It is only the external flesh that carries a barrier needing to be removed, unlike a non-Jew whose inner essence is characterized by that barrier [חתם סופר, פרדס יוסף].
