At the climax of the covenant at Mount Sinai, a practical sacrificial service was performed to ratify the acceptance of the Torah. This act combined the dedication of the people's servants with offerings of thanksgiving and peace, expressing the profound bond newly forged between God and Israel. The primary approach among commentators is that the young men tasked with this service were the firstborns of the Israelites. During this early period, before the construction of the Tabernacle and prior to the sin of the Golden Calf which later disqualified them, the holy service and the offering of sacrifices were exclusively the domain of the firstborns [רשב״ם, רש״י, מזרחי, שד״ל, בכור שור, קאסוטו].
The specific designation of these individuals as youths carries multiple layers of meaning. Some explain it as a contrast to the elders who are mentioned later in the narrative; while the elders were selected for their advanced age and wisdom, the firstborns were chosen solely by virtue of the sanctity of their birthright [רמב״ן, הכתב והקבלה, ביאור יש״ר]. Others suggest the title reflects their pristine spiritual state, describing them as pure, holy young men who had never tasted sin or approached a woman [רמב״ן, רבנו בחיי, טור הארוך]. Alternatively, the term does not necessarily indicate a young age at all, but rather functions as a title for servants, similar to the assistants of prophets. They served God in this holy capacity [הכתב והקבלה, רא״ש, קאסוטו, שטיינזלץ] and possessed the immense physical strength required to lift the sacrifices [אבן עזרא, חזקוני]. Historically, when the Torah was translated into Greek for King Ptolemy, this description was altered to "distinguished men" so the monarch would not mistakenly assume that the lowest members of society were sent to greet the Divine Presence. Nevertheless, some emphasize that it is precisely the youth of Israel who have always been the first to sacrifice themselves for their faith [תורה תמימה, פרדס יוסף]. Regarding their exact role, there is a view that Moses dispatched them to offer the sacrifices themselves [קאסוטו], while another perspective maintains that they merely prepared and positioned the offerings, leaving the actual sacrifice on the altar to designated individuals like Nadab and Abihu [מיני תרגומא, נתינה לגר].
The sacrifices themselves served as an expression of profound gratitude to God for the giving of the Torah and a celebration of the newly established covenant [שד״ל, רבנו בחיי]. Commentators highlight a fundamental distinction between the two types of offerings brought on this occasion. The burnt offerings were consumed entirely by the fire on the altar, symbolizing an absolute, unreserved dedication and the complete acceptance of the yoke of Heaven. In contrast, the peace offerings were divided: a portion was burned on the altar, another given to the servants, and the remainder eaten by those bringing the offering. This shared meal represents peace, joy, and a deep sense of closeness to God experienced directly within the material realm [רש״ר הירש, חומש קה״ת, שטיינזלץ].
A significant discussion surrounds the specific animals used for these offerings, particularly the bulls. One approach argues that only the peace offerings consisted of bulls, while the burnt offerings were sheep [מנחת שי, שד״ל, תורה תמימה, בכור שור]. Conversely, other commentators maintain that both the burnt and peace offerings were exclusively bulls [רמב״ן, רלב״ג, רקנאטי, אבן עזרא הקצר]. The selection of bulls is understood through several lenses. Practically, because the nation was so vast, large animals were necessary to provide sufficient meat for the communal feast of the peace offerings [אבן עזרא, ביאור יש״ר], with some calculating that exactly twenty-four bulls were brought, representing two for each tribe [אבן עזרא הקצר]. Symbolically, the bull is the largest of the domesticated species, making it the most fitting choice for a public sacrifice representing all of Israel [רלב״ג], and it embodies the concepts of labor and service to God that the nation had just embraced [רש״ר הירש]. Furthermore, as the Israelites wandered through the desolate wilderness, they harbored a constant fear of strict divine judgment. The offering of these powerful animals was specifically intended to appease and sweeten that harsh measure of justice [רמב״ן, רבנו בחיי, רקנאטי].
