Shared ground
This passage describes a required grain offering that belongs to the priests themselves (Aaron and his sons), not to ordinary Israelites. The text presents it as a regular, measured act of worship: fine flour mixed with oil, prepared on a pan, and offered morning and evening.
A key feature is that this priestly grain offering is not eaten. Instead, it is “wholly burned” to Yahweh and described as producing a pleasing smell. In the flow of Leviticus 6–7, that sets it apart from other offerings where priests receive a portion to eat.
The passage also stresses continuity: priestly service is ongoing through succession (“the anointed priest…from among his sons”), and the offering is treated as an enduring rule within Israel’s sanctuary system.
Where interpretation differs
How long “in the day when he is anointed” extends. Some read that phrase as marking the start date—from the anointing day onward the offering becomes part of the daily routine. Others read it more narrowly as tied directly to anointing, so that the anointing day is the main focus, even if the “perpetual” language still points beyond a one-day event.
Whether it is one daily offering for the priesthood or something each priest provides. The wording can be read as a single continuing priestly obligation carried by the current anointed high priest on behalf of the priesthood. Others think the language (“Aaron and his sons…every grain offering of a priest”) sounds broader and could imply that each priest, when inaugurated, has an associated obligation (whether daily for a term, or in connection with his installation).
How broadly the final line should be taken. “Every grain offering of the priest” may mean “every instance of this priestly grain offering category,” restating the rule just given. Or it may be read more expansively as a general principle: if a grain offering is offered by a priest for himself (not on behalf of another worshiper), it is not eaten but fully burned.
Why the disagreement exists
The passage uses both very specific instructions (amount, schedule, cooking method) and broad summary language (“statute forever…every grain offering of the priest”). Interpreters differ on whether the broad wording is meant as a tight summary of this one ritual or as a wider rule, and on how to coordinate “in the day when he is anointed” with “perpetually” and with priestly succession.
What this passage clearly contributes
Explicitly, it establishes a daily priestly grain offering with a fixed measure, divided morning and evening, prepared with oil, and fully burned to Yahweh. It also makes a clear distinction between offerings priests may eat and at least one priestly offering they may not. By inference, it highlights that priests, though they handle others’ gifts, are also obligated to offer to Yahweh and to do so in a way that does not provide them food from this particular offering (vv. 22–23).
