נחמיה, פרק י׳, פסוק ל״ט

Organizing the system of tithes and offerings was a central pillar in renewing Jewish life during the return to Zion. The community committed to a precise distribution process to ensure the economic survival of the Temple servants and to prevent any errors when separating the sacred gifts.

During the collection of these tithes, a Priest is required to be present alongside the Levite. The primary approach among commentators is that the Priest's presence serves as a direct form of supervision. Because the Priest's portion is embedded within the tithe received by the Levite, the Priest stands watch to ensure that the Levites do not withhold the share rightfully owed to the Priests [רלב״ג, מצודת דוד]. Alternatively, this arrangement is understood against a specific historical backdrop. Ezra the Scribe had penalized the Levites, thereby allowing the Priests to collect the initial tithe directly alongside them [מלבי״ם].

After receiving their tithe, the Levites are tasked with the physical and logistical work of separating a tenth of what they collected and transporting it to Jerusalem [רלב״ג, מצודת דוד, ביאור שטיינזלץ]. These provisions are brought directly to designated storage chambers within the Temple. Delivering the food straight to these storehouses guarantees that the Priests engaged in holy service are fully supported. By having their daily needs securely met on site, the Priests can remain entirely dedicated to their sacred duties without needing to leave their posts to gather food [רש״י, מצודת דוד].
