דברים, פרק י״ח, פסוק ח׳

The functioning of the Temple requires a delicate balance between the right of every priest to participate in the sacred service and the practical need to maintain a highly organized schedule. The right to partake in the offerings goes hand in hand with the right to perform the service itself [אדרת אליהו, העמק דבר]. The primary approach among commentators is that this equal distribution takes place specifically during the three pilgrimage festivals. During these times, all priests who travel to the Temple receive an equal share of the hides from the burnt offerings and the meat from the sin offerings. Some add that this equality extends to the distribution of the Showbread if the festival happens to fall on a Sabbath [תורה תמימה, מלבי״ם]. Interestingly, even a priest with a physical blemish who cannot actively perform the service still receives a portion of the offerings, provided he has reached the proper age for service [חזקוני]. Because he sits and guards the sacred vessels, he is likened to a soldier remaining at the rear who still shares in the spoils of war [קיצור בעל הטורים].

While the festivals grant equal rights to all visiting priests, a clear exception exists for the rest of the year. The prevailing view explains this exception through the historical division of the priests into twenty-four regular shifts. This arrangement stems from an ancestral agreement—established by leaders like David and Samuel—where priestly families essentially traded weeks of service, agreeing to take turns. Consequently, any offerings not related to a festival, such as the daily sacrifices, Sabbath additions, vows, and voluntary gifts, belong exclusively to the specific shift assigned to that week. A visiting priest cannot demand a share of these [רש״י, ספורנו, רלב״ג, בכור שור]. This structured division was designed to prevent disputes and confusion during the Temple service [רלב״ג], and some even view it as a wondrous reflection of the twenty-four shifts of ministering angels in the heavenly realms [רבנו בחיי]. Building on this framework, the ancestral agreement is sometimes understood as a system of constant rotation [הכתב והקבלה], or as a rule allowing a scheduled shift with a surplus of sacrificial meat to sell the extra portions to other priests [כלי יקר, שד״ל].

Beyond the shift system, other commentators interpret the exception as a safeguard for a priest's private property. If a priest sells his inherited family home or field and accumulates personal wealth, the other priests are forbidden from denying him his rightful share of the Temple offerings by claiming he is already wealthy and no longer needs the support [אבן עזרא, רבנו בחיי, חזקוני, ביאור יש״ר]. A third approach focuses on personal relationships and familiarity rather than financial transactions. According to this view, if a visiting priest arrives at the Temple during a week that is not his assigned shift, he may still participate if he knows someone on duty. If an ancestral relative currently serving agrees to hand over his own personal offering for the visitor to sacrifice, the visiting priest is permitted to perform the service, despite it being outside of his scheduled rotation [רשב״ם, חזקוני, הכתב והקבלה, ברכת אשר].
