ויקרא, פרק כ״ד, פסוק כ״א

Drawing a sharp contrast between harming an animal and harming a human establishes foundational principles in both tort law and capital cases. This comparison highlights a profound difference in the fundamental value of life. Animal life is considered property, meaning any harm caused to it can be rectified through financial compensation. In contrast, human life holds supreme and absolute value because humanity is created in the image of God. Therefore, harming a person can never be fully resolved with mere money, as human rights and freedoms are rooted in God's own free personality [רש״ר הירש].

Although similar laws appear earlier in the biblical text, their repetition introduces precise new rulings. The primary approach among commentators is that striking a person in this context refers only to inflicting a wound or bruise, rather than killing. Because an ordinary person is not sentenced to death for merely wounding a peer, this severe penalty is understood to apply specifically to someone who strikes their father or mother [רש״י, רשב״ם, מזרחי, מלבי״ם, בכור שור]. However, a contrasting perspective suggests the law deals with actual murder. Unlike previous laws that address immediate death from a blow to a vital organ, this scenario involves a person who strikes a victim in a non-lethal area, or a situation where the victim only succumbs to their injuries after some time has passed [אבן עזרא, חזקוני, רד״צ הופמן, שטיינזלץ].

The juxtaposition of striking an animal and striking a human serves as the source for several specific laws, particularly regarding parents. Just as financial compensation for an animal requires actual physical damage, the death penalty for striking a parent applies only if a physical bruise or wound is inflicted [רש״י, תורה תמימה, צפנת פענח]. Additionally, just as an animal is damaged while alive, a child is only liable if they strike their parents during their lifetime, exempting any blows dealt after death [רש״י, מזרחי, מלבי״ם]. The comparison also provides a medical exemption. Just as one may wound an animal to heal it, a child is permitted to draw blood from a parent for medical purposes without incurring any penalty [תורה תמימה]. Furthermore, the general terminology used for a person indicates that striking just one parent is sufficient to incur liability, without needing to strike both simultaneously [תורה תמימה, מלבי״ם, צפנת פענח].

Procedural and financial differences also emerge from this comparison. When an animal is harmed, the damage is assessed and paid immediately without waiting to see if the animal will eventually die. Conversely, when a human is struck, the attacker is held in custody until it becomes clear whether the victim will survive the injuries [העמק דבר]. Another major legal principle involves the exemption from financial payments in cases of severe punishment. While harming an animal always requires payment regardless of intent, committing an act against a human that warrants the death penalty entirely exempts the attacker from financial compensation. This remains true even if the act was accidental and the death penalty is not actually carried out [תורה תמימה, בכור שור, הכתב והקבלה, אדרת אליהו]. From a perspective of pure justice, one who wounds another should ideally receive a physical blemish measure for measure. However, because a human court cannot inflict such a punishment precisely without risking the offender's life, financial compensation is mandated instead [ביאור יש״ר, בכור שור].

Finally, the specific placement and repetition of these laws connect them directly to the subsequent mandate for a single standard of justice. This proximity emphasizes that these laws apply equally to the native citizen and the convert [אבן עזרא, רד״צ הופמן]. It also ensures that the level of scrutiny and rigorous investigation in a court of law must be identical, whether the judges are presiding over financial disputes or matters of life and death [רבנו בחיי].
