יחזקאל, פרק מ״ה, פסוק כ׳

Future guidelines for purifying the Temple reveal a fascinating tension between spiritual enthusiasm and the strict boundaries of holiness. A special atonement process is established to repair flaws created without malicious intent. Regarding when this takes place, the primary approach among commentators is that a sin offering is brought on the seventh day of the month of Nisan. However, others view this not as a single-day event, but as a continuous process of education and sacrifice spanning the entire first week of the month [רש״י, מצודת דוד, ביאור שטיינזלץ]. A unique perspective suggests that waiting until the seventh day serves as a period of spiritual preparation. Much like the High Priest secludes himself for seven days before the Day of Atonement to ensure absolute purity from past defilement, this waiting period guarantees readiness, even hinting that in the future, the Day of Atonement might actually occur in the month of Nisan [אהבת יהונתן].

The specific goal of this atonement is clearly defined by contrasting it with earlier actions. While the purification on the first day of the month is designed to atone for intentional sins, the actions on the seventh day are strictly for unintentional mistakes and a lack of awareness [מלבי״ם]. Interestingly, the root of these errors is actually profound joy. Swept up in the overwhelming enthusiasm of dedicating the altar, people might carelessly or accidentally wander into inner areas of the Temple where they are forbidden to enter [רד״ק, צאינה וראינה, אברבנאל].

Those who commit these accidental infractions fall into two distinct categories. The first is an individual who makes an intellectual error; this is an educated person who simply draws the wrong conclusion or issues an incorrect legal ruling [מלבי״ם, מצודת ציון]. The second is a simple person who trespasses purely out of ignorance [מלבי״ם, מצודת ציון]. Ultimately, the sanctuary itself must be wiped clean and purified from the desecration caused by the unauthorized entry of these individuals [רש״י, אברבנאל, מצודת דוד, מצודת ציון]. Once the Israelites achieve atonement for their missteps, the physical Temple is simultaneously cleansed and atoned for [רש״י].

Alongside this literal understanding, a rich layer of interpretation based on the Talmud shifts the focus from a specific date to a national event. In this view, the details of the date are entirely symbolic. The number seven represents seven tribes of Israel, while the concept of the month alludes to a new, yet mistaken, legal ruling issued by the High Court—such as accidentally permitting the consumption of forbidden fats. Because seven tribes constitute a majority of the community's tribal groups, even if they do not make up the absolute majority of the population, their collective error based on the court's misguidance requires a special communal sin offering [רש״י, רד״ק, חומת אנך, אברבנאל].
