Scripture Text
Thesis
Aaron offers the peace offerings for the people, sprinkles the blood, burns the fat, and waves the designated portions before Yahweh.
Verse by Verse
Slaughter, blood handling, and altar application Aaron kills the ox and the ram as the people’s peace offerings. His sons bring him the blood, and Aaron applies it around the altar, indicating a full-circuit placement rather than a single spot.
Listing the fat portions to be removed The text names the internal “fat” portions to be set aside: the fat tail, the covering over the insides, the kidneys, and the long lobe/covering connected with the liver. The point is not cooking detail but which parts are treated as a special share.
Arrangement and burning of the fat The fat portions are placed on top of the breasts, and then Aaron burns the fat on the altar. This describes a two-step handling: first stacking/placing, then turning the fat portion into smoke at the altar.
Literary Context
These verses sit in the opening day of priestly ministry after Aaron and his sons have been set apart for service (chapter 8) and then instructed for this inaugural ceremony (chapter 9). The chapter moves through a sequence of offerings: first sacrifices for Aaron himself, then offerings “for the people,” concluding with this peace offering segment. Within that flow, vv. 18–21 focus on what is done with the blood, the best internal portions, and the portions presented before Yahweh and then kept. The repeated note that actions occur “as Moses commanded” ties the scene back to prior instructions and emphasizes careful performance rather than improvisation.
Historical Context
The scene assumes Israel is gathered in the wilderness camp with a functioning tabernacle system and an active priesthood just beginning its public work. Sacrifices are described in concrete, practical steps: slaughter, collection and delivery of blood, application at the altar, and handling of meat and fat portions. The passage reflects a world where communal worship often involved animal offerings, shared meals, and designated shares for cult personnel. Here, Aaron’s sons assist by handling and delivering blood, while Aaron performs the key altar actions and the public presentation of portions before Yahweh.

Waved portions and obedience to instruction The breasts and the right thigh are waved before Yahweh as a “wave offering,” and the narrative closes by saying this was done as Moses commanded. The wave action marks these pieces out by a formal presentation, distinct from what is burned on the altar.
These verses show the peace offering as a carefully ordered ritual carried out by the newly installed priesthood. Aaron kills the animals for the people, his sons assist by bringing the blood, and Aaron applies the blood to the altar all around it (explicit). The best internal portions (“fat,” kidneys, and the liver-related covering) are set apart and burned on the altar (explicit), while the breasts and right thigh are not burned but are formally presented before Yahweh by a “wave” action (explicit).
The passage also highlights role-sharing: the sons handle support tasks, while Aaron performs the key altar actions and the public presentation (inference from the sequence). The repeated “as Moses commanded” underscores that acceptable worship here means following the given instructions rather than improvising (explicit).
What the “wave” action looked like. The text says the breasts and right thigh were “waved” before Yahweh, but does not describe the motion. Some think it involved lifting and moving the portion in a visible presentation; others think it may have been a more limited gesture of raising or extending it before the altar.
What exactly “the cover of the liver” refers to. Translations and explanations differ on whether this means a particular lobe, a membrane, or an attached fatty piece. The passage’s main point, though, is that a specific liver-associated portion is reserved for the altar.
Why the fat is placed “on the breasts” before burning. Some read this as a practical staging step (setting the fat on the meat before transferring it to burn). Others think it signals a moment of presentation: the priestly portions (breast/thigh) are marked out, while the fat portion is then burned to Yahweh.
The Hebrew ritual terms are brief and assume shared knowledge of tabernacle practice. The passage narrates actions without explaining mechanics, and later instructions elsewhere in Leviticus give categories of portions without always spelling out the gesture details. That leaves room for reconstruction from language, comparison with nearby passages, and reasonable guesses about ceremony.
It clarifies that the peace offering involves both an altar portion (fat and specified internal parts burned) and presented portions (breast and right thigh waved before Yahweh). It also shows the priesthood functioning as mediator for “the people,” with blood applied around the altar and with certain portions formally designated for Yahweh and for priestly handling, all under the authority of the instructions given through Moses (Leviticus 9:21).
