ויקרא, פרק י״א, פסוק א׳

Following the construction of the Tabernacle and the dedication of the priests, a new framework is established for the daily lives of the Israelites through dietary laws and rules of purity. These instructions are not designed to promote physical health, as other nations consume all types of food and still maintain robust health. Instead, their purpose is the healing and elevation of the soul [שד״ל, כלי יקר, אברבנאל]. The food a person consumes directly impacts their mental clarity and inner character. By avoiding impure foods, a person undergoes a process of spiritual refinement that prevents mental dullness and cruelty, ultimately preparing the Israelites to be a holy nation intimately connected to God [רש״ר הירש, כלי יקר, אברבנאל]. Furthermore, introducing the dietary laws before the general rules of impurity serves to demonstrate that the holiness of the ordinary Israelites is equal to that of the priests. Purity is a demand placed upon the entire nation, not just those who serve in the sanctuary [אלשיך].

The communication of these laws is directed to both Moses and Aaron. Aaron's inclusion stems from the fact that the laws of purity and impurity are fundamental to the priestly duties. The priests must constantly guard themselves against impurity so they can enter the sanctuary and consume the holy offerings. Additionally, they bear the responsibility of teaching the Israelites to distinguish between the holy and the everyday, and between the pure and the impure [רמב״ן, אבן עזרא, הטור הארוך, ביאור יש״ר, שטיינזלץ, פירושי רד״צ הופמן]. Including Aaron in this divine communication also serves as a gesture of reconciliation, appeasing him after Moses expressed anger toward him and his sons regarding the sin offering in the preceding events [רלב״ג].

Regarding how this message was delivered, the primary approach among commentators is that God actually spoke only to Moses, instructing him to relay the words to Aaron [רש״י, מזרחי, ריב״א, שפתי חכמים, ביאור יש״ר, העמק דבר]. However, others suggest that the divine communication was directed to both leaders equally [רשב״ם, נתינה לגר], while another perspective proposes that an angel emerged from the divine speech to address both of them simultaneously [אור החיים].

The intended recipients of these instructions also spark different interpretations. One approach suggests that the message is directed toward Aaron's surviving sons, Eleazar and Ithamar. Although Moses had previously been angry with them, their respectful silence earned them the privilege of becoming religious teachers for the nation. Addressing them directly emphasizes that their standing is just as significant as that of their deceased brothers, Nadab and Abihu [רש״י, מלבי״ם, ביאור יש״ר, משכיל לדוד, העמק דבר, אדרת אליהו]. Another viewpoint maintains that the message simply refers back to Moses and Aaron, reinforcing that the command was intended for both of them [רשב״ם, אור החיים]. A third perspective views this as a general introduction to the commands that were subsequently to be taught to the entire Israelite nation [אברבנאל, אלשיך]. Taking a distinct approach, one commentator suggests that the instructions specifically exclude the other nations of the world. Because the dietary laws are intended to purify the soul for the afterlife rather than provide physical health benefits, they are exclusively relevant to the Israelites, who are destined for eternal life. To prevent anyone from mistakenly viewing these laws as mere medical advice, it is emphasized that these instructions are meant uniquely for the Israelites [כלי יקר].
