במדבר, פרק י״ח, פסוק א׳

In the aftermath of Korah's rebellion and the plague that followed, the Israelites were gripped by profound anxiety. They feared that merely approaching the Tabernacle would result in death. To calm the nation and firmly establish the boundaries of the sacred space, God clarifies that the burden of preventing such disasters does not rest upon the common people, but rather on the designated holy officials.

Although the divine communication is directed toward Aaron, the primary approach among commentators is that the message was initially delivered to Moses, who was tasked with conveying it to Aaron. This indirect routing addresses the fact that the people's earlier panicked complaints about the danger of the sanctuary were directed at Moses. Furthermore, since the instructions involve distancing the entire Israelite camp from the holy areas, Moses necessarily had to be included. Conversely, some scholars maintain that because these directives are fundamentally priestly laws entrusted to Aaron, God communicated with him directly, without Moses acting as an intermediary [מלבי״ם, ברכת אשר].

The responsibility is divided into two distinct circles. The first encompasses Aaron, his descendants, and his extended ancestral family. While Aaron and his sons clearly represent the priests, the exact identity of the extended family is subject to different interpretations. The prevailing view is that it refers specifically to the Kohathite family, who were responsible for carrying the sacred vessels of the Tabernacle and are thus included in this strict warning [רש״י, מזרחי, העמק דבר, שטיינזלץ, ברכת אשר]. Other scholars broaden this group to include the entire tribe of Levi [אבן עזרא, מלבי״ם, ביאור יש״ר]. A different perspective suggests this is a personal address to Moses, indicating that even he is bound by the warning to respect the sacred boundaries where the priests operate [אור החיים].

This initial group is charged with accountability for the sanctuary. Most commentators explain this as an outward-facing duty. The priests and Levites are required to stand guard, warning and preventing ordinary Israelites or impure individuals from approaching the holy vessels. Should the guards prove negligent, allowing an unauthorized person to accidentally trespass, the guilt and subsequent punishment fall squarely upon the priests and Levites. Alternatively, another approach views this responsibility as an internal matter concerning the integrity of the divine service itself. Rather than merely keeping outsiders away, the officials are held accountable for their own mistakes, lapses in concentration, or improper intentions during the service, such as throwing the sacrificial blood or burning the fats without the proper mindful focus on God [רש״ר הירש, מלבי״ם, צפנת פענח].

The second circle of responsibility is narrower, focusing exclusively on the priests. Aaron and his sons are instructed together, emphasizing that they share this burden constantly and equally; there is never a moment where the obligation rests on only one of them [אור החיים]. They are tasked with protecting the strict integrity of the priesthood. This is predominantly understood as the priests' duty to supervise the Levites, ensuring they do not overstep into the specific tasks reserved for the priesthood, thereby maintaining a clear separation of roles [רש״י, ספורנו, אבן עזרא, ביאור יש״ר, רקנאטי].

Other commentators interpret this inner circle of responsibility as a warning against flaws the priests might introduce into their own service [רלב״ג, העמק דבר, שטיינזלץ]. Specifically, it serves as a caution against compromising the sanctity of the priesthood through greed or selfishness. A priest must not take his portion of the sacrificial meat before the blood is thrown or the fats are burned. Doing so would mean forgetting that his sustenance comes from a divine source, turning sacred worship into a pursuit of personal profit that degrades the sanctuary [רש״ר הירש, מלבי״ם]. Lastly, a unique interpretation proposes that carrying this heavy burden is not about facing punishment at all. Instead, it signifies forgiveness, indicating that the priests, through the faithful execution of their duties, generate atonement and pardon for the entire nation [שד״ל].
