The first day of the seventh month marks a unique intersection in the biblical calendar. On this day, known as Rosh Hashanah, three distinct systems of offerings converge one after the other: the standard daily offering, the additional offerings for the New Moon, and the special festival offerings unique to the new year [רש"י, ביאור שטיינזלץ]. This three-part combination represents three different sources of spiritual elevation. The morning light testifies to God, the renewal of the moon signifies cyclical rebirth, and the blast of the shofar calls for return and repair. Together, these elements unite to express a deep sense of humility and a dedication of life to God's laws [רש"ר הירש].
The specific sequence of these offerings establishes a fundamental rule regarding the Temple service: a frequent offering always takes precedence over an infrequent one. Consequently, the daily offering is brought first, followed by the monthly New Moon offering, and finally the annual Rosh Hashanah offering [רלב"ג].
A significant detail in the instructions for this day is the explicit mention of the New Moon burnt offering, while the New Moon sin offering is entirely omitted. One approach suggests this prevents a potential misunderstanding. A person might mistakenly assume that the special Rosh Hashanah offerings cancel out or replace the standard New Moon ones. To prevent this, the instructions emphasize that the festival offerings are brought in addition to the monthly ones. Once the burnt offering is mentioned, it is self-evident that all New Moon commandments, including the sin offering, remain fully in effect, making it unnecessary to explicitly list the sin offering as well [רמב"ן, הטור הארוך].
However, the primary approach among commentators attributes this omission to a fundamental difference between the types of offerings. The burnt offerings for the New Moon and Rosh Hashanah are grouped together because they share the exact same purpose: both atone for the failure to perform positive commandments. In contrast, the sin offerings for these two occasions are designed to atone for entirely different categories of unintentional sins, which vary based on a person's level of awareness before and after the act. Because of this stark difference in the nature of the atonement, the New Moon sin offering is not mentioned in the same breath as the Rosh Hashanah offerings [ריב"א, בכור שור, חזקוני, דעת זקנים, הדר זקנים].
This intentional omission led the Talmud to refer to Rosh Hashanah as a holiday where the month is "covered," since the Torah deliberately concealed the sin offering from the text. This observation sparked a fascinating debate regarding the text of the additional Rosh Hashanah prayer. Some scholars, such as Rabbeinu Tam, amended the prayer to explicitly mention "two he-goats," ensuring both the New Moon and Rosh Hashanah sin offerings were recognized. Conversely, others, like Rabbi Netanel, strongly opposed this addition. They argued that if the Torah specifically chose to hide and conceal this offering, it is inappropriate to publicly broadcast it in prayer [דעת זקנים, הדר זקנים].
Finally, the concluding details regarding the accompanying libations refer to the special wine libations of Rosh Hashanah, along with the wine and meal offerings that accompany the New Moon and daily burnt offerings [חזקוני]. Notably, the term for the meal offering is written with a missing letter. This subtle omission hints that the entire period stretching from Rosh Hashanah through the end of the Sukkot festival is a continuous span during which the Israelites are judged for their livelihood. This prolonged period of judgment is compared to an extended pregnancy that has not yet reached its conclusion [העמק דבר].
