Leviticus / Question
Leviticus states that no grain offering presented to the LORD may be made with leaven, and it also prohibits burning honey as a food offering. The rule is given as a direct restriction on what may be turned into smoke on the altar. The chapter distinguishes this from certain firstfruits presentations (Leviticus 2:11–12).
Leviticus 2:11–13 sets boundaries on what may accompany a grain offering brought to Yahweh. It bans yeast and honey from anything burned on the altar, while allowing them in a different setting: a firstfruits offering that is presented but not turned into smoke on the altar. In contrast to these exclusions, salt is required. These verses conclude the instructions for the grain offering within the opening block of Leviticus that explains how Israelites may bring offerings to the tabernacle (Leviticus 1–7).
These verses set clear boundaries for what can and cannot accompany a grain offering brought to Yahweh. Two ingredients—yeast and honey—are excluded from anything that is burned on the altar. By contrast, salt is not optional: it must be included with every grain offering. The text also draws an important procedural distinction.
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 2:11-12, then read the surrounding section so the answer stays connected to the passage's flow.
11No meal-offering, which you shall offer to Yahweh, shall be made with yeast; for you shall burn no yeast, nor any honey, as an offering made by fire to Yahweh.
12As an offering of first -[fruits] you shall offer them to Yahweh: but they shall not come up for a sweet savor on the altar.
