ויקרא, פרק כ״ב, פסוק ז׳

The journey from ritual impurity back to a state of holiness involves more than just physical immersion in water; it requires the passage of time. For a priest seeking to return to his sacred duties, the setting of the sun and the appearance of stars mark a profound transition. Under Jewish law, nightfall introduces a new day, automatically lifting certain restrictions and allowing the priest to resume eating holy food [ביאור יש״ר, ביאור שטיינזלץ].

The primary approach among commentators is that this renewed purity does not require the priest to perform any additional cleansing actions the following day. Rather than an ongoing process requiring further intervention, purity is achieved automatically the moment the sun sets, signaling that the previous day and its limitations have completely ended [מלבי״ם, הכתב והקבלה, תורה תמימה, אבן עזרא].

However, this evening return to holiness is only partial. While the priest is now permitted to consume consecrated food, commentators emphasize that this allowance applies only to certain types of sacred offerings [רש״י, מזרחי, ברטנורא]. Specifically, it permits him to eat the basic priestly portion, which serves as his standard agricultural gift. Even if the priest had contracted a severe level of impurity, he may eat this portion immediately in the evening without waiting until the next morning to offer a formal atonement sacrifice. In contrast, consuming meat from altar sacrifices remains strictly forbidden until that final sacrifice is brought [ספורנו, גור אריה, חזקוני, ברכת אשר].

This distinction between types of holy food also governs the laws of mixtures. If the basic priestly portion blends with ordinary, non-sacred food, it may still be eaten under specific conditions. Yet, if even a minute amount of altar sacrifice mixes into the basic portion, a priest who has not yet brought his atonement sacrifice is forbidden to eat it, as the stricter laws of the altar sacrifices immediately take effect [תורה תמימה, אדרת אליהו, פרדס יוסף].

The reasoning behind this leniency, which allows the priest to eat his basic portion immediately at nightfall, is rooted in deep consideration for his well-being. Unlike sacrificial meat, which is viewed as a meal shared from God's own table, the basic priestly portion is the priest's essential daily sustenance. God did not wish to impose an extreme hardship that would leave the priest hungry until the following day [רלב״ג, העמק דבר, רש״ר הירש, פירושי רד״צ הופמן]. Beyond simple physical nourishment, some explain this sustenance on a spiritual level. A priest inherently yearns for holiness and feels incomplete without it; therefore, he is allowed to reunite with his sacred calling at the earliest possible moment [פרדס יוסף].

Recognizing this portion as the priest's standard food also defines how he is allowed to handle it in his kitchen. He is permitted to prepare it just as he would any ordinary meal, whether by sifting wheat or chopping vegetables. At the same time, because the food remains inherently sacred, even the discarded scraps and vegetable peelings retain their holy status. They must be treated with respect and cannot be carelessly destroyed or discarded like ordinary refuse [תורה תמימה, מלבי״ם, אדרת אליהו, צפנת פענח].
