Society's true moral character is tested by how it treats its most vulnerable members. Following the warning against mistreating a foreigner, biblical law extends a protective shield over those who lack natural support systems and the power to defend themselves against aggressors [קאסוטו, חזקוני]. The essence of a widow's vulnerability lies in her profound loss; having functioned as one body with her husband, she is now left without her vital counterpart [הכתב והקבלה]. Furthermore, she has lost the advocate who once spoke on her behalf. Similarly, the orphan experiences a tragic severing, having lost the guiding and supporting hand of a father [רש״ר הירש].
The primary approach among commentators is that this protection applies to every widow and orphan, even those who are wealthy and own property. Their emotional state is fragile, their tears come easily, and they remain highly susceptible to pain [רמב״ן, הטור הארוך, ביאור יש״ר, אלשיך]. However, differing perspectives exist regarding how broadly to apply this rule. One view suggests that the widow and orphan merely serve as common examples of any weak or oppressed individual, reflecting the everyday reality of those who lack strength and are prone to suffering [רש״י, גור אריה, תורה תמימה, מלבי״ם, דברי דוד]. In contrast, another approach limits this severe prohibition strictly to literal widows and orphans, maintaining its strict application even if the woman is the widow of a king [מלבי״ם, פרדס יוסף].
Oppression in this context encompasses any form of harm, including anger, teasing, causing heartache through harsh words, inflicting financial damage, or exploiting their inherent weakness [רלב״ג, רש״ר הירש]. The suffering inflicted on them often carries a dual nature. Beyond the immediate pain of the offense, the mistreatment serves as a cruel reminder of their loss, forcing them to realize that if their loved ones were still alive, no one would dare harm them [אלשיך]. This double affliction can also manifest in institutional settings, such as when a judge unnecessarily delays an orphan's trial and subsequently withholds their funds until a guardian is appointed [אדרת אליהו]. However, commentators emphasize a crucial exception: if causing distress does not stem from malice but is intended to educate, discipline, and ultimately benefit the orphan, it is considered an act of kindness. Even then, great care must be taken not to burden them beyond what is absolutely necessary [ספורנו, העמק דבר, פרדס יוסף].
The responsibility to protect these vulnerable individuals extends far beyond the direct offender. A bystander who witnesses the mistreatment of an orphan or widow and remains silent is considered an oppressor themselves and shares in the guilt [אבן עזרא, חזקוני, הטור הארוך, העמק דבר]. This collective duty is directed at the entire nation, the general public, and the courts. Society as a whole must act as the "father of orphans," actively supervising and preventing any individual from exploiting the weak [שד״ל, תורה תמימה, מלבי״ם].
Because the anguish of the widow and orphan is magnified, their cry to God is equally intense. Consequently, God's attentiveness to their pain is absolute, leading to severe punishment [אלשיך, אדרת אליהו]. The consequence for this sin is not a standard divine death sentence, but rather death by the sword in battle or in a distant land, ensuring the oppressor's burial place remains unknown. This creates a devastating, measure-for-measure outcome: without proof of death, the offender's wife becomes perpetually unable to remarry, and his children remain permanent orphans who cannot inherit his estate. The person who cruelly reminded a widow and orphan of their loss is punished by leaving his own family in an unresolved state of grief, where his absence will never be forgotten [רמב״ן, צאינה וראינה, הדר זקנים, אלשיך].
