The Torah addresses a grim scenario: one person strikes another, and the victim's survival is uncertain. The verse states that if the injured party recovers, "the striker shall be absolved." The Mekhilta probes what exactly happens during the period of uncertainty between the blow and the recovery.
One might assume that "absolved" means the striker goes free immediately after striking, perhaps posting guarantors or bail while waiting to see whether the victim lives or dies. The Mekhilta rejects this reading. The striker does not simply walk away with a promise to return for judgment.
Instead, the text establishes that the striker is incarcerated. He sits in custody, waiting. The key phrase is "If he arise and walk outside," referring to the victim. Only when the injured person physically gets up and walks around outside, demonstrating genuine recovery, is the striker released. Until that moment, the one who delivered the blow remains confined.
This ruling reveals the seriousness with which the Torah's legal system treats bodily harm. The striker is not presumed innocent during the waiting period. He is held in a state of legal suspension, his fate tied directly to the fate of his victim. If the victim recovers, the striker is absolved and pays only for lost work time and medical expenses. If the victim dies, the case transforms into a potential capital matter.
The Mekhilta's interpretation ensures that no one who inflicts serious bodily harm can simply return to normal life while their victim lies suffering. The incarceration is not punishment. It is accountability, a physical reminder that violence has consequences that cannot be deferred or delegated to guarantors.
