ויקרא, פרק כ״ה, פסוק ט״ו

In ancient Israel, real estate transactions operated under a unique system where land was never sold permanently. Because ancestral tracts automatically returned to their original owners during the Jubilee year, a land sale was essentially a long-term lease. The buyer did not purchase the earth itself, but rather acquired the rights to harvest its crops until the upcoming Jubilee [תורה תמימה]. This temporary transfer of agricultural rights carries distinct legal implications, such as affecting a farmer's ability to make the traditional declaration when bringing first fruits.

The primary approach among commentators is that this framework serves as a strict warning against fraud and price gouging. Since the land eventually reverts to the seller, the purchase price must be precisely calculated based on the exact number of harvest years remaining until the next Jubilee [רש״י, ספורנו, רלב״ג, שטיינזלץ]. The directive addresses both parties simultaneously, ensuring neither takes advantage of the other. Buyers are cautioned against exploiting a seller's financial desperation or falsely claiming that fewer years remain. Conversely, sellers are warned not to deceive buyers by hiding upcoming Sabbatical years, during which the land must lie fallow and yield no crops [העמק דבר, ביאור יש״ר, רש״ר הירש]. This mutual accountability ensures that even if the land is resold to a third party, the new buyer is fully aware of the Jubilee restrictions and cannot claim permanent ownership [שפתי חכמים, דברי דוד]. From a moral standpoint, this system encourages both the buyer and the seller to actively protect each other's rights, calculating a fair price that benefits everyone involved [אלשיך].

Although a property's value is dictated by the time remaining until the next Jubilee, the calculation is framed conceptually around the years that have passed since the previous one. Commentators offer several explanations for this perspective. Some note that counting the years elapsed since the last Jubilee naturally reveals how many remain [מזרחי], while others suggest this framework simply means looking ahead toward the upcoming Jubilee [הכתב והקבלה]. Additionally, this establishes that no real estate transactions may take place during the Jubilee year itself [ספורנו, רלב״ג, הכתב והקבלה]. It also accommodates special circumstances: if a field is purchased very close to the Jubilee, or leased for a specific, extended period like sixty years, the buyer's rights do not automatically expire when the Jubilee arrives. Instead, their ownership continues past the Jubilee until the agreed-upon term is completed [אור החיים, פני דוד, מלבי״ם].

A foundational rule governing these sales is that a seller cannot redeem, or buy back, their field before at least two full years have passed from the date of the transaction [רש״י, מזרחי, תורה תמימה]. This is based on the requirement that a sale must encompass a plural number of crop years, which is legally defined as exactly two [משכיל לדוד]. This minimum period ensures the buyer has adequate time to utilize and benefit from the land. Unlike a residential home, where a single day of occupancy constitutes use, a field's value is only realized through a full cycle of sowing and reaping across two agricultural seasons [גור אריה]. Furthermore, this restriction forces a landowner to carefully consider the sale of their ancestral heritage, knowing they cannot simply change their mind and reverse the transaction immediately [אור החיים]. It also serves to protect the buyer's initial labor and financial investment in the field [הכתב והקבלה].

Crucially, these two years must be capable of producing a harvest. Sabbatical years, or periods of severe drought and crop blight, do not count toward this minimum requirement and must be made up later, with the Sabbatical years appropriately deducted from the land's overall purchase price [ספורנו, חתם סופר, תורה תמימה, ברכת אשר]. However, if the transaction involves rocky, unfarmable terrain or the sale of mature trees rather than arable land, the two-year waiting period does not apply, and the property can be redeemed immediately [תורה תמימה, אדרת אליהו]. For standard agricultural fields, the two years are calculated with absolute precision from the exact calendar day of the sale. Even if a highly efficient buyer manages to harvest three separate crops within that timeframe, the field remains in their possession until the full two calendar years have completely elapsed [רש״י, תורה תמימה].
