After establishing a foundation of civil laws and justice, the focus shifts toward commandments built on kindness, grace, and sacred times. These laws go beyond strict justice, serving as a reminder of the covenant made with God [שד״ל, קאסוטו]. The instruction to engage in agricultural work for six years is not an independent rule. Rather, it serves as a necessary introduction to the Sabbatical year of rest, highlighting the sharp contrast between seasons of labor and a season of complete rest [אבן עזרא, חזקוני, קאסוטו]. Working the land involves physical labor [ביאור שטיינזלץ], and gathering the harvest specifically means bringing the crops indoors for personal use. This stands in complete opposition to the seventh year, when the produce is left outside and ownerless in the field [רשב״ם, רש״י, מזרחי, ביאור יש״ר].
The cycle of working for six years and resting on the seventh is designed to uproot human pride. By leaving the harvest for the poor and wild animals, people are reminded that God is the true owner of the land, while humans are merely temporary residents in His domain [רש״ר הירש]. Furthermore, this cycle is closely tied to earlier warnings against oppressing strangers. Observing the Sabbatical year protects the nation from the punishment of exile, preventing them from ever having to taste the bitterness of being strangers in a foreign land again [אור החיים].
The personal nature of this agricultural cycle is highly specific. Unlike the Jubilee year, which applies collectively only when all the tribes dwell in the land, the Sabbatical year is an individual obligation that remains binding even if only a single farmer remains in Israel [פרדס יוסף]. Additionally, the assurance that the land belongs to the individual emphasizes that once the year of rest concludes, the property returns fully to the farmer's control. This differs from the Jubilee year, when lands are confiscated and returned to their original ancestral owners to demonstrate absolutely that the earth belongs to God [רבנו בחיי].
The primary approach among commentators addresses why there is a need to instruct people to plant their fields for six years, as this is a natural and expected activity. The accepted explanation is that this is not a mere instruction, but a powerful divine blessing and promise. Because the farmer observes the Sabbatical year, God grants the soil a special strength to yield crops for six consecutive years. The farmer will not need to leave the field fallow every other year, as is common in regular agriculture [העמק דבר, תורה תמימה, מלבי״ם, אלשיך]. Conversely, another perspective suggests that there is a constant, practical duty to cultivate every available plot of land in Israel, even a small ruined patch in a garden, in order to maximize the opportunity to separate tithes and offerings [דעת זקנים].
On a deeper spiritual level, the six years of planting symbolize a person's lifespan and their actions in this world. When an individual engages in commandments and good deeds, the world is truly considered their own and is deemed worthy of having been created for them. Consequently, the act of gathering the harvest represents collecting the spiritual reward that is reserved for a person in the afterlife [שפתי כהן].
