The days inaugurating the Tabernacle demand absolute physical and spiritual devotion from Aaron and his sons. The instruction to remain at the entrance of the sanctuary day and night for a full week establishes a profound level of holiness and discipline. The primary approach among commentators is that this does not require sitting continuously without a single break, as human beings must attend to their basic physical needs. Rather, the priests are instructed never to leave the Tabernacle complex during their designated working hours or abandon their service midway. This sets a permanent precedent prohibiting a priest from leaving the Temple while actively serving [רמב״ן, רבנו בחיי, הטור הארוך, צאינה וראינה, פרדס יוסף]. Commentators compare this continuous presence to the commandment of dwelling in a sukkah, where the temporary structure becomes one's primary residence for holy matters, yet one may briefly step out for essential necessities [ביאור יש״ר]. Practically, the curtains of the Tabernacle remained fully erected throughout this period without being dismantled [ספורנו], and the priests likely managed the demanding schedule by dividing their time into shifts [ביאור שטיינזלץ].
The requirement to keep God's charge encompasses both physical and spiritual duties. On a physical level, it mandates an honor guard to protect the sanctuary's sanctity and prevent the entry of anything impure, a duty that could be maintained even while resting or sleeping [פרדס יוסף, רד״צ הופמן, ביאור שטיינזלץ]. Spiritually, this guard duty represents a complete dedication to internalizing the profound ideas embedded within the Tabernacle [רש״ר הירש]. It also requires a deep, intensive study of the Oral Law to ensure the service is performed flawlessly and without error [העמק דבר, נתינה לגר]. Furthermore, this directive establishes the broader obligation to create boundaries and protective measures around the Torah's commandments [תורה תמימה].
A severe warning accompanies these instructions, cautioning the priests that failure to comply will result in death. Commentators explain this through deductive reasoning: God is not merely stating the obvious fact that obedience preserves life, but rather emphasizing the strict penalty. If the priests fail to follow the rules with absolute precision, they will be liable to death [רש״י, מזרחי, שפתי חכמים, גור אריה, אבן עזרא]. The meticulous guard duty and preliminary study act as the essential guarantees that they will not fail in their service at the altar and incur this fatal consequence [העמק דבר]. Moses concludes these directives by clarifying that he acts directly on God's orders. Even though the specific details of this seven-day dwelling were not explicitly recorded in earlier instructions regarding the Tabernacle, Moses assures them that this mandate came directly from God [ביאור יש״ר, העמק דבר, אבן עזרא]. This clarification also serves to encourage the priests. Moses urges them to fulfill the command now under his direction, for which they will be rewarded, reassuring them that they will receive an even greater reward in the future when God commands them directly to guard the Temple [מלבי״ם].
Beneath the practical instructions lies a chilling foreshadowing of the future. The seven days of dwelling quietly hint at the impending seven days of mourning for Aaron's sons, Nadab and Abihu, who are destined to die on the eighth day. God, knowing the future, essentially commands the priests to observe a preliminary period of mourning. This mirrors how God Himself mourned for seven days before bringing the Flood upon the earth, teaching that the passing of righteous individuals is as devastating before God as the destruction of the entire world [רבנו בחיי, תורה תמימה, צאינה וראינה, שפתי כהן]. On a personal and allegorical level, this narrative offers profound guidance for human existence. The seven days symbolize the seventy years of an average human lifespan. The directive to never leave the Tabernacle's entrance is a lifelong call to maintain an unwavering focus on serving God. It urges a person to live every single day as if it were their last, carefully keeping God's charge, and thereby earning true, eternal life [חתם סופר].
