A seamless transition from the laws of animal sacrifices to the laws of charity reveals a profound perspective on the nature of ownership. Just as an individual is commanded to share the meat of a peace offering rather than consuming it alone, a person must share the harvest of their field with the poor. The land and its produce are ultimately a gift from God. Leaving a portion of the crop for the impoverished and the stranger serves as an acknowledgment of His ultimate ownership over creation. This practice fosters a society built on kindness, justice, and peace, directly addressing and preventing feelings of frustration and the temptation of theft among the destitute [שד״ל, חזקוני, רד צ הופמן, אלשיך, העמק דבר].
The responsibility of this Commandment speaks to both the collective and the individual. While the act of harvesting is often carried out by many workers, the ultimate responsibility and warning rest squarely on the shoulders of the single property owner [רבנו בחיי, אלשיך]. This emphasizes that even a person with a very small field is obligated to contribute, preventing the excuse that a modest donation is meaningless [אור החיים]. Furthermore, the obligation includes fields owned by Jewish partners, highlighting the underlying unity of the Israelites [תורה תמימה, צרור המור].
The obligation takes effect under very specific conditions. It applies only when the reaping is done intentionally by the Jewish owner, excluding crops taken by non-Jews, stolen by robbers, or consumed by animals and insects [תורה תמימה, הכתב והקבלה, חזקוני]. The harvest itself must consist of produce like grain or legumes that are fit for human consumption, grow from the earth, are gathered all at once rather than gradually over days, and are stored for the long term [תורה תמימה, רש ר הירש, רלב״ג]. The method of gathering is broad; the rules apply whether the crop is cut with a traditional sickle or uprooted by hand [תורה תמימה, מלבי״ם]. Furthermore, this specific Torah duty applies exclusively within the Land of Israel, and a portion must be separated from each individual field, excluding ownerless lands or those owned by non-Jews [תורה תמימה, רלב״ג, ביאור יש״ר].
Rather than completely clearing a field for personal gain, an owner must leave the corner or edge of the field unharvested for the poor [רש״י, שטיינזלץ, ביאור יש״ר]. The primary approach among commentators is that this portion should be left specifically at the end of the field, at the very conclusion of the harvest. This timing is rooted in four moral and social considerations: it prevents the owner from secretly calling a poor relative to take the produce before others arrive; it removes suspicion from passersby who might otherwise think the owner is stingy; it saves the poor from wasting their entire day waiting to see when the portion will be allocated; and it prevents deceitful owners from claiming they already left a portion elsewhere. Nevertheless, if an owner does leave the corner at the beginning or middle of the harvest, the obligation is still considered fulfilled [מזרחי, תורה תמימה, גור אריה, בכור שור].
Alongside the unharvested corner, there is a requirement regarding gleanings—individual stalks that slip from the reaper's hand or sickle and fall to the ground during the harvest [רש״י, שטיינזלץ, רלב״ג]. This rule only applies when the stalks fall naturally due to the act of reaping, rather than from a sudden disruption like a thorn prick, a scorpion sting, or an unexpected startle [תורה תמימה, מלבי״ם]. A specific quantity defines these gleanings: one or two stalks falling together are reserved for the poor, but if three fall at once, they remain the property of the field owner [רש״י, מזרחי, צאינה וראינה]. The owner is strictly forbidden from gathering these fallen stalks, even with the intention of giving them to a specifically favored poor person. They must remain on the ground so that any impoverished individual can come and collect them with dignity, free from direct dependence on the landowner's personal charity [שטיינזלץ, מלבי״ם, אלשיך].
Beyond the immediate social benefits, these agricultural laws contain a deep spiritual dimension. Their placement immediately following laws concerning severe spiritual punishment teaches a profound lesson about redemption. Even a person who has sinned and distanced themselves from God should never despair or abandon the Commandments. Leaving the gleanings and the corner of the field establishes a root of holiness within the physical earth, keeping a pathway open for repentance [אור החיים]. Ultimately, the restraint required to not gather every last piece of the harvest teaches humanity not to greedily consume all the abundance provided in this world, but to consciously leave behind merit, resources, and blessing for future generations [שפתי כהן].
