במדבר, פרק ט׳, פסוק ב׳

The command to offer the Passover sacrifice in the wilderness marks a profound historical transition, turning the one-time event of the Exodus from Egypt into an eternal law. Following the detailed instructions regarding the specific duties of the Priests and the Levites in the Tabernacle, the focus shifts to a commandment that belongs to the entire public, acting as a shared duty that unites Priests, Levites, and ordinary Israelites alike [צרור המור].

This directive serves several purposes for the Israelites. On an emotional level, it acts as a source of comfort. After watching the tribal leaders offer their exclusive sacrifices for the dedication of the Tabernacle, the people felt a deep sadness, feeling left out of the grand celebration. In response, God gives them the Passover sacrifice as an equal commandment for every person to fulfill with joy [שפתי כהן]. At the same time, the command acts as a necessary warning. The Israelites were so completely absorbed in the joy of building the Tabernacle and dedicating the altar that there was a real concern they might excuse themselves from the Passover duties due to the overwhelming schedule of celebrations. Therefore, the obligation to perform it immediately is heavily stressed [ספורנו, הכתב והקבלה]. Furthermore, this instruction uproots a common misconception among the people that the Passover sacrifice was only meant for the actual night they left Egypt. Tragically, despite this clarification, this was the only Passover the Israelites would observe throughout their entire forty years of wandering in the wilderness [רשב״ם, שפתי כהן].

A central theme of this commandment is its strict adherence to a specific schedule. The obligation to offer the sacrifice at its exact set time applies to the Israelites even while they are still wandering in the wilderness, well before entering the land [העמק דבר]. The primary approach among commentators is that this establishes a fundamental law: the Passover sacrifice must be offered precisely when scheduled, and this requirement is so absolute that it overrides both the holiness of the Sabbath and a state of ritual impurity.

However, the permission to perform the sacrifice in a state of impurity is highly specific. It is limited strictly to impurity caused by contact with a dead body, and it only applies when the majority of the public or the Priests are impure. An individual who becomes impure cannot participate at that moment; instead, they are pushed off to the following month to observe a Second Passover [תורה תמימה, שפתי חכמים, מזרחי, גור אריה].

There is a deep conceptual meaning behind this rigid timing. An appointed time represents a fixed, unique meeting with God. Because of this, offering the sacrifice on the Sabbath is not viewed as a violation of the holy day, but rather as its ultimate fulfillment. Furthermore, the permission to proceed despite contact with death is granted specifically to the public because a collective nation, unlike a single fragile individual, is eternal. It does not die, and therefore its inner essence remains forever elevated above the impurity of death [רש״ר הירש].
