In this passage, Moses addresses Aaron and his sons, Eleazar and Ithamar, following a tragic event where Aaron's other sons, Nadab and Abihu, were consumed by fire for offering unauthorized fire before the Lord. Moses instructs them to partake in the grain offering that remains from the food offerings. This grain offering, prepared without yeast, is designated as most holy, emphasizing its sanctity and the priests' responsibility to handle it with reverence.
Consuming the offering beside the altar signifies the priests' integral role in the worship and sacrificial system, highlighting their duty to uphold the holiness of the offerings. This act of eating the offering is not merely a physical act but a spiritual one, symbolizing their participation in the holy service and their connection to God. It serves as a reminder of the importance of obedience to God's commands and the sacred nature of their priestly duties.
