בראשית, פרק מ״ז, פסוק כ״ו

A nation's survival during a severe famine often requires sweeping economic changes. Joseph’s emergency measures in Egypt eventually evolve into a permanent legal framework, defining state land ownership and establishing a lasting tax system, while carving out a unique exemption for the religious class. He establishes this arrangement as a permanent law, ensuring it cannot be easily overturned [רש"י, ביאור שטיינזלץ]. However, he only cements the policy into Egyptian law after proving to the citizens that the system is entirely fair. By doing so, he ensures the tax is viewed as a just national policy rather than an arbitrary act of robbery [ספורנו].

The core of this law requires the people to give one-fifth of their harvest to the king [ביאור יש"ר]. A profound legal concept lies at the heart of this structure. The land technically belongs to Pharaoh, but only as a guarantee to ensure the payment of the twenty percent tax. If a farmer fails to pay, the crown has the right to confiscate the property entirely. This specific arrangement protects the Egyptians from becoming mere slaves or lowly serfs who receive only a fraction of their own hard work. Instead, they remain independent farmers who retain four-fifths of their crop to support themselves [רש"ר הירש].

A single group is excluded from this national tax system: the Egyptian idolatrous priests [אבן עזרא, מחוקקי יהודה]. Their land remains in their possession and does not transfer to state ownership because their special status entitles them to direct financial support from the king [ביאור שטיינזלץ]. Beyond serving as a historical record, detailing this specific exemption carries a psychological and educational message for future generations. By highlighting the universal respect and financial security granted to religious servants in ancient Egypt, the narrative prepares the Israelites for their own future obligations. It serves to prevent any resentment among the people regarding the numerous gifts and tithes they will eventually be commanded to provide to their own priests [שד"ל].
