ויקרא, פרק ב׳, פסוק ט״ו

The final laws regarding grain offerings detail the preparation of the first-fruits offering, known as the Omer. Although this is a mandatory requirement for the entire public, its rules are placed alongside voluntary, individual grain offerings. This arrangement is necessary because the preparation process for the Omer is highly unique and demands specific attention. Furthermore, grouping a public obligation with private donations teaches that a mandatory offering must be brought with the exact same spirit of willingness and dedication as a voluntary gift. Alternatively, this placement hints that during the future times of exile, the practice of bringing the Omer would be temporarily paused [רש ר הירש, רד צ הופמן].

The physical preparation of the first-fruits is similar to that of a standard fine flour offering. Oil is poured directly onto the fine flour [רלב״ג, ביאור יש״ר]. Frankincense is then placed on a small portion of the offering, and the priest takes it from that spot before performing the ritual scooping of the flour [ביאור יש״ר]. The instructions emphasize that this is a complete grain offering, meaning its preparation methods are identical to those of any regular fine flour offering [ביאור יש״ר, רש ר הירש, ביאור שטיינזלץ].

Beyond the practical steps, the precise instructions for this public offering contain numerous legal boundaries regarding other public grain offerings [מלבי״ם]. The requirement to add oil and frankincense stems from the very definition of the sacrifice as a grain offering, rather than simply because it consists of first-fruits. Because of this underlying rule, the special grain offering brought on the eighth day of the Tabernacle's dedication also requires both oil and frankincense [תורה תמימה, מלבי״ם, חזקוני, אדרת אליהו].

Conversely, specific limitations in the instructions exclude other public offerings from needing these additions. The Showbread is excluded from the requirement of oil, even though it serves as a symbol of the nation's food. Similarly, the libation grain offering does not require frankincense, despite symbolizing the dedication of human property to God [תורה תמימה, מלבי״ם, אדרת אליהו, רד צ הופמן]. Finally, the Two Loaves brought on the holiday of Shavuot are entirely excluded; even though they are classified as a grain offering, they are prepared without any oil or frankincense at all [תורה תמימה, מלבי״ם, רש ר הירש, אדרת אליהו].
