ויקרא, פרק כ״ב, פסוק כ״ג

The laws of animal offerings demand absolute physical perfection, ensuring that gifts presented to God are flawless. Yet, a fascinating distinction arises regarding animals born with specific physical deformities, highlighting the difference between dedicating an animal for actual sacrifice and donating its financial value to the Temple. Certain congenital defects render an animal unfit for the altar. For instance, an animal might suffer from an overgrown or dislocated limb, or even possess extra appendages [רש״י, מזרחי, תורה תמימה, רלב״ג, אבן עזרא]. Conversely, it might have a stunted, shrunken limb [שטיינזלץ, אבן עזרא], or hooves that are entirely fused together like those of a horse or donkey, lacking the split hooves required of a pure animal [רש״י, רשב״ם, בכור שור, הירש]. Furthermore, the explicit mention of different types of livestock teaches that the prohibition against offering blemished animals applies universally to all possible defects, not just the specific deformities highlighted [תורה תמימה, מלבי״ם, אדרת אליהו].

A straightforward reading might mistakenly suggest that an animal with such deformities could be brought to the altar as a spontaneous freewill offering, though forbidden as the fulfillment of a formal vow. However, Jewish law strictly prohibits offering any blemished animal on the altar under any circumstances. Therefore, the primary approach among commentators is that the distinction being made is not between different types of altar sacrifices, but rather between different destinations for the dedicated property. A deformed animal may be given as a freewill offering to the Temple treasury for general upkeep. In this case, the animal is simply sold, and the proceeds are used to maintain the physical structure of the sanctuary. Conversely, the strict prohibition against bringing such an animal as a vow refers specifically to dedicating it for the altar itself, where a flawed animal can never be accepted [רמב״ן, רש״י, ספורנו, רשב״ם, הכתב והקבלה].

The choice of terminology reflects human nature and common practice. Donations for the maintenance of the Temple building are typically spontaneous, freewill offerings driven by generosity, as there is no formal obligation to donate property for this purpose. Altar sacrifices, on the other hand, are frequently the result of vows made during times of distress, where a person formally obligates themselves to bring an offering [רמב״ן, מזרחי, העמק דבר, הכתב והקבלה, גור אריה]. Additionally, righteous individuals generally avoid making formal vows to prevent the sin of failing to fulfill them on time, preferring instead to make spontaneous freewill donations for Temple upkeep. However, regarding the altar, even the most pious individuals sometimes take formal vows, such as when accepting the restrictions of a Nazirite [משכיל לדוד].

While the practical law follows the distinction of where the animal is donated, an alternative perspective focuses on a more literal understanding of the text. If a person points to a specific, deformed animal and declares it a freewill offering, they have technically kept their word, as their original intent was focused on that exact animal. However, if they make a general vow to bring an offering and later present a blemished animal, they fail to fulfill their obligation, because a general vow implicitly assumes a proper, unblemished animal [בכור שור, חיזקוני, ביאור יש״ר].

On a conceptual level, this distinction highlights the different nature of the two types of dedication. Donating an animal for Temple upkeep is purely a financial transaction. While a physical defect lowers the animal's market value, it does not prevent it from being sold for the benefit of the treasury [ספורנו]. An altar sacrifice, however, is a profound expression of a person's devotion to God. Since the animal symbolically represents the person offering it, it must be entirely whole and unblemished to reflect a complete, perfect desire and absolute dedication to Him [רש״ר הירש].
