Taking advantage of the vulnerable is a grave moral failure, especially when the victims are orphans who lack a natural support system. While defenseless people may appear as easy targets in this world, exploiting their weakness carries severe consequences [אמרי דעת]. In ancient society, a close relative typically held the legal right and duty to protect family members and recover their lost property [מלבי״ם]. Because orphans lack a flesh-and-blood relative to stand up for them, God Himself steps in. He assumes this legal and fatherly responsibility, acting directly as the father of the orphans and the protector of their property [ביאור שטיינזלץ, אלשיך].
This dynamic creates a sharp contrast in power. The orphans themselves may be weak and exhausted, but their heavenly protector is infinitely stronger than any human oppressor. He is the one who will personally confront anyone who tries to harm them [מצודת דוד, רלב״ג]. The primary approach among commentators is that God will never leave such an injustice unanswered; He manages the conflict Himself, ensuring that the oppressor faces justice [מלבי״ם].
This divine intervention operates on several deep levels [אלשיך]. First, God assumes a dual role in the heavenly court: He is both the judge who decides the verdict and the prosecutor who actively represents the orphans. Second, the punishment goes far beyond mere financial loss. Because God is the one fighting the battle, the consequence strikes at the oppressor's very body and soul. After consulting His heavenly court, God punishes the oppressor with his very life as a penalty for tormenting the vulnerable.
The pain of an exploited orphan is twofold. The child cries out because of the theft itself, but also because the abuse awakens the deep, fresh pain of being fatherless—knowing that if his father were alive, no one would dare treat him this way. God hears both of these cries and demands justice for both the financial wrong and the emotional insult [אלשיך].
Furthermore, the rules of divine justice adapt to protect the defenseless. Generally, an ordinary person who appeals directly to the heavenly court faces danger, as his own past actions are scrutinized first. Orphans, however, are not penalized for taking their grievances directly to heaven. Because God is their dedicated protector, they can cry out to Him safely and immediately. Ultimately, the sin of harming an orphan is so severe that it causes God's attribute of mercy—the very source of benevolent protection—to flip completely. It transforms into a fierce, vengeful force that relentlessly fights the oppressor [אלשיך].
