ויקרא, פרק כ״ה, פסוק ג׳

The agricultural rhythm in Israel requires a delicate balance between intensive labor and absolute surrender to Divine providence. The directive to work the earth for six consecutive years forms the foundation of the Sabbatical year, establishing the boundaries of human ownership and reliance on nature. The primary approach among commentators is that this directive functions as a prohibition derived from a positive command. God permits working the land for exactly six years, meaning that anyone who farms during the seventh year violates both a positive and a negative commandment [רמב״ן, טור, אור החיים, תורה תמימה].

Beyond the legal framework, this continuous labor contains an extraordinary Divine promise. In the natural order, farmers must periodically leave their fields fallow so the soil does not lose its fertility. However, the farmers of Israel are assured that they can plant the exact same plot for six consecutive years without the earth weakening [ספורנו, אור החיים, פענח רזא, כלי יקר]. This intensive cycle demands immense trust in God. A farmer who lacks faith and leaves his field barren out of fear of depleting the soil actually misses the true purpose of the land, which yearns to yield its strength for those who serve God [חתם סופר, נחלת יעקב]. Furthermore, the very privilege of farming one's own field is a reward for recognizing God's ultimate ownership during the Sabbatical year. Those who refuse to release their grip on the land will be punished with exile, forced to work the fields of strangers [כלי יקר, תולדות יצחק].

The agricultural work extends beyond sowing fields to pruning the branches of vineyards and olive groves [ביאור יש״ר, שטיינזלץ, רד״צ הופמן]. The distinct mention of both field crops and tree fruits highlights an essential legal difference in how their agricultural years are calculated. Grains and vegetables are categorized based on the time they are harvested, whereas the status of tree fruits is determined by the moment they bud and begin to form [אור החיים].

The culmination of this six year cycle is the gathering of the yield, a term that encompasses both the produce of the earth [אבן עזרא, רש״ר הירש, רד״צ הופמן] and the fruit of the vines [פענח רזא]. Legally, this yield only refers to crops that have ripened to at least a third of their full growth [תורה תמימה, אילת השחר, מלבי״ם]. The act of gathering underscores the profound difference between the six years of labor and the Sabbatical year. During the working years, people are instructed to harvest their crops, bring them into the granary and winepress, and accumulate them for trade and personal wealth [רשב״ם, ביאור יש״ר, שטיינזלץ]. In stark contrast, during the seventh year, all produce is declared ownerless and must be eaten directly from the field [כלי יקר, העמק דבר].

The legal definition of the yield also dictates the transition into the Sabbatical year. If a crop reaches a third of its growth before the new year of the seventh year begins, it is considered part of the six year cycle and may be gathered into the home even during the Sabbatical year itself [תורה תמימה, רלב״ג, מלבי״ם]. Finally, while this gathering is generally intended for standard human consumption and commerce, extreme circumstances can alter the rules. In times of emergency, such as when a ruling government demands a heavy crop tax, the sages permitted planting and gathering even during the Sabbatical year to preserve human life [אור החיים].
