The grain offering is made from fine flour, with oil poured on it and frankincense placed on it. A “memorial portion” is burned on the altar, and the rest belongs to Aaron and his sons. Leviticus lists multiple preparation forms, including baked or cooked versions (Leviticus 2:1–3; Leviticus 2:8–10).
Leviticus 2:1–3 describes a basic grain (meal) offering. A person brings fine flour and adds oil and frankincense, then brings it to the priests. The priest takes a handful portion and burns it on the altar as the “memorial” portion, producing a pleasing smell to Yahweh. These verses sit in Leviticus’ opening sequence of instructions about different kinds of offerings (Leviticus 1–7). After the whole-burnt offering in the previous chapter, this section turns to a non-animal gift focused on grain and scent.
Leviticus 2:1–3 presents a grain-based gift brought “to Yahweh” through the priests. The offerer supplies fine flour with oil and frankincense (explicit). The priests handle it: a priest takes a handful portion of the flour and oil, along with all the frankincense, and burns that portion on the altar (explicit).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Leviticus 2:1-3, then read the surrounding section so the answer stays connected to the passage's flow.
1"`When anyone offers an offering of a meal-offering to Yahweh, his offering shall be of fine flour; and he shall pour oil on it, and put frankincense on it.
2He shall bring it to Aaron`s sons the priests; and he shall take his handful of its fine flour, and of its oil, with all its frankincense; and the priest shall burn the memorial of it on the altar, an offering made by fire, of a sweet savor to Yahweh.
3That which is left of the meal-offering shall be Aaron`s and his sons`. It is a most holy thing of the offerings of Yahweh made by fire.
