Transitioning from the laws of purity to the regulations of slaughter and sacrifices marks a crucial step in shaping the holiness of the nation, deliberately distancing them from spiritual impurity and the worship of demons [ספורנו]. Although these instructions revolve around the Tabernacle, they fundamentally govern the daily lifestyle of the entire public. Consequently, the directive is addressed to both the spiritual leadership and the general populace [ביאור שטיינזלץ].
The comprehensive address to Aaron, his sons, and all the Israelites reflects a specific division of responsibilities regarding the strict prohibition against offering sacrifices outside the Tent of Meeting. The priests are warned not to perform sacrifices outside, while the Israelites are instructed to bring their offerings exclusively to the priests rather than attempting to sacrifice them independently [רמב״ן, הטור הארוך, ביאור יש״ר]. The priests are explicitly mentioned either because they were the ones who practically carried out the slaughtering for the Israelites during the desert wanderings [אבן עזרא, חזקוני], or to emphasize that despite certain exemptions they enjoy during the inner service of the Tabernacle, they are subject to the full punishment if they slaughter outside its precincts [תורה תמימה]. Furthermore, these laws apply equally to converts and servants [רלב״ג, תורה תמימה, אדרת אליהו]. However, the restriction against outdoor slaughtering is exclusive to the Israelites; gentiles are permitted to build personal altars and offer sacrifices on them, though Israelites are forbidden from assisting them in this practice [תורה תמימה].
The instruction is presented as something God had already commanded previously, but which is only now being publicized to the nation [פירושי רד״צ הופמן]. The primary approach among commentators is that this legislation addresses the consumption of secular meat eaten simply to satisfy hunger. During the years of wandering in the desert, the Israelites were completely forbidden to eat meat unless the animal was first brought to the Tabernacle as a peace offering to God. It was only later, upon entering the Land of Israel, that the consumption of secular meat was permitted anywhere, even as the ban on offering sacrifices outside the Temple remained strictly in force [רמב״ן]. While the basic reading seems to target only the desert generation, the emphasis on God having commanded it serves to teach that the core laws of sacrifices remain applicable for all generations [העמק דבר]. On a spiritual level, bringing the animals to the Tabernacle with the proper verbal intentions serves to rectify and elevate reincarnated souls trapped within the animals, ultimately rescuing them from the forces of impurity [שפתי כהן].
The direct manner in which the command is delivered highlights Moses' unique style of prophecy, which differed from the methods of other prophets [צפנת פענח, אדרת אליהו]. Because the impending law is exceptionally severe—going so far as to equate the slaughter of an animal outside the Tabernacle with literal bloodshed—there was a genuine concern that the people might assume Moses invented the rule from his own mind merely to frighten them. To prevent this, it is stressed that these are the exact words heard directly from God [ביאור יש״ר].
An essential legal principle is also derived by comparing the delivery of this law to the laws of vows. Commentators explain that just as a sage has the authority to annul a vow, a person can also seek the annulment of a consecration. If an individual slaughters a sacrificial animal outside the Tabernacle and incurs the severe penalty of spiritual excision, they can approach a sage to have the animal's consecrated status evaluated. If the sage finds valid grounds for regret and annuls the consecration, it is retroactively established that the animal was never actually holy, thereby exempting the person from the severe punishment [תורה תמימה, העמק דבר, אדרת אליהו].
