The act of providing charity and offering loans extends far beyond a simple transfer of money. It serves as a profound spiritual and moral test that intimately connects the giver, the receiver, and God, ensuring the continued flow of abundance in the world. This act of generosity impacts not only the physical well-being of the impoverished but also the very soul of the wealthy and the spiritual balance of the universe.
The obligation to give is constant and unceasing, requiring one to offer support even a hundred times if necessary [רש״י, רבנו בחיי, מלבי״ם]. This duty is so universal that even a poor individual who relies on charity for their own survival must set aside a portion of their meager funds to help others [תורה תמימה, אלשיך]. The primary approach among commentators is that as a person repeatedly engages in acts of giving, the trait of generosity becomes deeply rooted within their character. In response, God increases their wealth, granting them further abundance so they can continue to give [אבן עזרא, נחל קדומים, תולדות יצחק]. True charity requires paying close attention to the specific needs of the individual, providing exactly what they lack [בעל הטורים]. Crucially, this support should be offered in secret, remaining a private matter between the giver and the receiver to spare the impoverished person any feelings of shame [רש״י, מלבי״ם, רש ר הירש, תורה תמימה, ברכת אשר].
Beyond the physical action, the internal mindset of the giver is of utmost importance. Providing assistance with a sense of distress, anger, or fear of financial loss fundamentally damages the Commandment. Instead, one must offer help with a pleasant face, genuine joy, and without any harsh words or scolding [רבנו בחיי, העמק דבר, תולדות יצחק, ביאור שטיינזלץ]. A person is expected to harness their entire being—both their positive and negative inclinations—toward this goal. Once an individual trains themselves to understand that charity ultimately brings personal blessing and profit, even their selfish impulses will agree with the act and cease to resist it [אלשיך, נחלת יעקב]. There is no reason to fear financial loss or the cancellation of debts during the Sabbatical year, because the wealth a person gives away is merely a heavenly deposit entrusted to them specifically for the poor [רא״ש, חזקוני, אלשיך, ביאור שטיינזלץ].
The mechanics of this divine blessing operate through two distinct but complementary avenues. First, the world functions like a turning wheel, where wealth and poverty constantly rotate among people. God designed reality this way to remind humanity that they are only temporary residents in a world that belongs entirely to Him. By giving charity, a person ensures that when the wheel of fortune inevitably turns, they or their descendants will be treated with mercy [כלי יקר, רבנו בחיי, תורה תמימה, שפתי כהן]. Second, the divine reward applies not just to the physical transfer of money, but to speech and intention. A person who genuinely intended to give but was prevented by circumstance, one who persuades others to contribute, or even someone who simply comforts a poor person with kind words, earns tremendous blessing. In fact, comforting words bring a greater flow of blessing than the money itself, and the heartfelt blessing the poor person offers in return impacts the wealthy giver even more than the money helps the poor [רש״י, מזרחי, העמק דבר, מלבי״ם, דברי דוד, רש ר הירש].
Ultimately, charity is so essential that it bridges the gap between strict justice, represented by the poor, and divine mercy, represented by the wealthy, thereby sustaining the entire world [רבנו בחיי]. One who has the privilege to give should feel as though they are nourishing a limb of their own body [אבי עזר]. In the merit of such complete and proper giving, God promises that His blessing will rest upon every area of a person's life, whether they are engaged in manual labor and agriculture, or commerce and business [העמק דבר].
