God's communication to Moses introduces a distinct section within the broader laws of offerings. After detailing the general rules for grain offerings, God initiates a new address to set apart the unique offering required of Aaron and his sons. Because the priests receive a steady income provided by God, they are commanded to present a regular grain offering of their own. This act serves as a constant reminder that they are God's servants, sustained directly at His table [רד צ הופמן].
This specific requirement encompasses two related practices. First, it includes the dedication offering, which every priest brings on his very first day of service. Second, it includes the daily baked grain offering, which the High Priest presents every day, offering half in the morning and half in the evening. While the instructions might seem to present a contradiction by describing the offering both as an event tied to the day of anointing and as an ongoing daily requirement, the primary approach among commentators resolves this tension smoothly. The obligation simply begins on the day a priest is anointed for his role. From the moment he enters his position, the requirement takes effect, and the offering is brought every single day.
Although the High Priest is the one who physically presents this daily offering, it is named for Aaron and all his sons. This is because the High Priest does not bring it solely on his own behalf. Instead, he acts as an authorized representative and messenger for the entire community of priests [רד צ הופמן].
