Offerings brought to the altar are often accompanied by a precise measure of wine, poured out as a dedicated act of worship. This pouring is not a random spilling of liquid, but a careful, intentional placement. The wine is never poured directly onto the altar's fire, as God commanded that the flames must not be extinguished. Instead, it is poured into designated bowls fixed at the southwestern corner of the altar. From these vessels, the wine flows downward through specific holes deep into the altar's foundations [רש״ר הירש, ביאור יש״ר, שטיינזלץ]. While the wine and the accompanying grain offering are presented together, they remain independent; if one is unavailable, the other may still be offered on its own [רש״ר הירש].
The required measurements for these accompanying elements are strictly defined based on the type of animal. The specified amount applies exclusively to a young sheep in its first year, rather than to older animals of the same species [העמק דבר]. The primary approach among commentators is that this specific measurement dictates not only the volume of the wine but also the amounts of the grain and oil brought alongside it. These precise quantities are unique to a young sheep, whereas larger animals, such as rams and bulls, require entirely different measurements [רש״י, גור אריה, שטיינזלץ].
When an individual vows to bring multiple offerings, the accompanying libations cannot be grouped together. A person is not permitted to bring a single, large measure of wine to cover all the animals at once. Rather, a distinct and separate libation must be provided for every individual offering, whether it is a burnt offering or another type of sacrifice [חזקוני, מלבי״ם, ברכת אשר].
The requirement to bring libations alongside various types of sacrifices highlights a unique scenario involving a person purifying from a spiritual skin disease. This individual must bring a burnt offering alongside mandatory sin and guilt offerings. Usually, sin and guilt offerings are not accompanied by wine libations, because the offering of a sinner should not be beautified. However, the person recovering from this affliction is an exception. Since the intense suffering of the disease has already provided atonement for the underlying sin of harmful speech, the individual is no longer viewed as an active sinner when bringing the sacrifice. Therefore, these specific sin and guilt offerings are elevated and require libations [מלבי״ם, תורה תמימה].
Furthermore, the rules governing these libations extend to special cases where only a single sheep is offered. One such instance is the burnt offering brought by a woman after childbirth. Another, more unusual case involves the tithing of animals. If a person counting their flock mistakenly points to the eleventh animal and declares it the tenth, that eleventh animal instantly becomes holy. It is then brought as a peace offering and must be accompanied by a wine libation, even though the actual tithed animal itself does not require a libation at all [תורה תמימה, העמק דבר, מלבי״ם].
