After four years of anticipation and discipline, during which the yield of a newly planted tree is either entirely forbidden or restricted to sacred consumption in Jerusalem, a profound shift occurs in the fifth year. This marks a year of release. For the first time, the farmer is permitted to enjoy the fruits of their labor without restriction, transitioning the tree to a regular status for everyday use [ביאור יש״ר, ביאור שטיינזלץ]. However, this permission is not always absolute; occasionally, fruit picked during this fifth year remains forbidden if it initially blossomed during the fourth year [העמק דבר, אדרת אליהו].
Alongside this newfound freedom comes a profound guarantee of exceptional economic blessing. The primary approach among commentators is that this represents a promise of divine abundance: those who meticulously observe the initial restrictions will be rewarded with a multiplied harvest [רש״י, רשב״ם, רלב״ג, אבן עזרא, בכור שור, פירושי הופמן]. Beyond simple agricultural success, this assurance addresses a deep psychological challenge. It speaks directly to human nature, preventing the frustration and sorrow of toiling for four years without personal benefit. The promised surge in yield compensates for the lost years, proving that the prolonged restraint is ultimately worthwhile [רש״י, תורה תמימה, משכיל לדוד, מלבי״ם, הכתב והקבלה, בכור שור].
This divine guarantee also serves a practical agricultural purpose. Naturally, a farmer seeking to strengthen a young tree might pluck and destroy its early blossoms so the tree can conserve energy for superior future harvests. There is a specific concern that a farmer might do this during the fourth year to avoid the burden of redeeming the crop or traveling to Jerusalem, hoping instead to maximize profits in the unrestricted fifth year. By promising a supernatural abundance, God encourages the farmer to fulfill the requirements of the fourth year rather than destroying the early growth [חתם סופר]. Furthermore, the promise of natural prosperity was designed to eradicate ancient idolatrous customs, which involved performing obscene rituals on trees to artificially hasten their yield [רלב״ג].
A careful distinction is made between the early stages of growth and the final harvested crop. While early growth refers to the developing stages on the branch, the eventual harvest represents the fully ripened yield ready to be brought into the storehouse [מלבי״ם, אילת השחר]. This distinction indicates that the restrictions of the fourth year cannot be lifted through redemption until the crop is completely ripe [תורה תמימה, אדרת אליהו]. Moreover, the promise of an increased yield carries an economic implication of gathering and accumulation. Unlike the yield of the fourth year, which is designated solely for eating and cannot be sold, the harvest of the fifth year may be gathered into storehouses for commerce, allowing the farmer to build personal wealth and capital [ביאור יש״ר, העמק דבר, הכתב והקבלה].
The conclusion of this process is sealed with a personal guarantee from God, testifying to His faithfulness in fulfilling this promise of blessing [רש״י, פירושי הופמן]. Such a reminder is essential at this exact moment due to the immense difficulty of exercising a four-year restraint. A farmer who watches their orchard bear fruit but cannot partake of it needs a constant reminder of Who issued the command in order to find the strength to persevere [ביאור שטיינזלץ, בכור שור]. Ultimately, this establishes a vital moral boundary: a person must not observe the Commandments merely to attain the promised wealth, but rather out of a sincere acceptance of God's decrees and His ultimate sovereignty [העמק דבר, פענח רזא].
