Earlier instructions regarding the sacrifices focused on the Israelites who brought them, addressing their personal motives, whether driven by duty or a voluntary spirit. Now, the attention shifts directly to the priests who physically perform the service [הטור הארוך, רש ר הירש]. Because of this fundamental change in audience, the arrangement of the sacrifices changes as well. They are no longer organized by the reason they are brought, but rather by their level of holiness. The instructions begin with the most sacred offerings, such as the burnt and sin offerings, and conclude with those of a lesser holy status, like the peace offerings [רלב״ג, רש ר הירש].
The direct address to Aaron before his sons is deeply intentional. In previous instructions, his sons were mentioned first, which might have raised questions about Aaron's own standing. Here, God clarifies the matter by granting Aaron special honor, placing him firmly at the head of the command [הטור הארוך]. Furthermore, the language used to deliver these instructions is unusually forceful. Rather than using standard terms for speaking or saying, the instruction relies on a word denoting a strict command. This expresses absolute authority and an undeniable obligation to carry out the order [מלבי״ם]. The primary approach among commentators is that this forceful language carries three specific legal and conceptual requirements: it demands immediate execution, establishes a permanent law for all future generations, and requires a special level of urgency and strict attention from those being commanded [מלבי״ם, אלשיך].
The need for such intense urgency in this specific context is explained through two complementary approaches. One perspective points to practical difficulties. Naturally, extra motivation is needed when fulfilling a duty involves a financial loss. While the priests typically receive portions of the sacrifices, in this instance, they are required to provide a daily grain offering from their own personal funds. Additionally, the exhausting, grinding physical labor involved in the daily sacrificial service is viewed as a heavy burden comparable to a financial loss. Therefore, a strong push is necessary to ensure the priests do not become negligent [הטור הארוך].
A second, more spiritual approach explains that this urgency is meant to instill a deep sense of awe. There is a natural danger that the priests might become numb to their daily routine, eventually treating God's altar as just another ordinary platform for presenting gifts. The firm command serves to awaken them to the greatness of their role. It reminds them that the earthly altar aligns with a heavenly one and is sustained by a spiritual fire. Recognizing this reality requires the priests to approach every task with intense holiness, deep reverence, and supreme swiftness [אלשיך]. Ultimately, this mindset reveals the broader purpose of the entire sacrificial service: to help a person elevate their mind and soul above physical desires, drawing them closer to spiritual perfection and the true service of God [רלב״ג].
