ויקרא, פרק י״ז, פסוק י״ד

The prohibition against consuming blood rests on a profound spiritual and moral foundation: the intrinsic connection between blood and the life force. Because humanity does not possess absolute dominion over the essence of life itself, consuming blood—which embodies life—disrupts the very order of creation [ביאור שטיינזלץ]. The primary approach among commentators is that blood is not the actual soul, but rather stands in its place, as the vitality of the living being is entirely dependent upon it [רש"י, מזרחי, שפתי חכמים, אור החיים, רד"צ הופמן]. Conversely, others suggest that the blood and the life force are inextricably blended within the living body, much like wine diluted in water, with the blood actively generating and sustaining the creature's vitality [רמב"ן, שד"ל]. Another perspective simply understands the essence of the creature as residing directly within its blood [חזקוני].

Consuming blood carries severe spiritual and psychological consequences. Because blood contains the essential vitality and inherent nature of the creature, ingesting it introduces a wild, bestial element into the human body. This act damages the refined human and divine soul, ultimately corrupting a person's moral character [ספורנו, העמק דבר, ביאור יש"ר, רלב"ג]. This spiritual reality dictates the scope of the prohibition: while the blood of animals and birds is strictly forbidden, the blood of fish is permitted. The nature of fish does not negatively impact the human soul in the same manner, nor is their life fluid classified as forbidden blood in the biblical sense [ביאור יש"ר, אם למקרא].

The broader communication of this law to the entire Israelite nation serves multiple purposes. While some view it as a reminder of an earlier command [אבן עזרא, חזקוני], others understand it as a comprehensive social and legal mandate. It calls upon the community and the courts to take collective responsibility, ensuring that individuals do not stumble into this transgression [מלבי"ם, אילת השחר]. The prohibition is specifically expanded to include wild animals and birds, which are not offered on the altar. Since the blood of domesticated animals is used for atonement, its sacred restriction is deeply ingrained in the public consciousness. However, one might mistakenly assume that the blood of wild creatures is permitted. To prevent this error, the restriction is emphasized, accompanied by the command to cover the spilled blood with earth [חזקוני, פירושי רד"צ הופמן]. This act of covering is also rooted in morality; just as humanity shows respect for the deceased through burial, one must respectfully conceal the blood that once housed a living soul [אור החיים, מלבי"ם].

Although the act of consuming forbidden blood might involve many individuals, the severe spiritual punishment of being cut off is strictly personal. This individual focus clarifies that only the specific sinner bears the punishment, without transferring guilt to the broader community [אור החיים, ברכת אשר, פירושי רד"צ הופמן]. On a deeper, mystical level, the solitary nature of the punishment reflects the reality of human consumption. When a person eats, multiple facets of their being—body, spirit, and soul—derive pleasure from the food. Yet, the resulting punishment strikes at a single, critical point: it severs the solitary, elevated thread of the soul that connects the individual to God [אור החיים].
