ויקרא, פרק כ״א, פסוק ח׳

The responsibility for maintaining the sanctity of the priesthood does not rest solely on the priests themselves; it is placed directly upon the shoulders of the entire nation and its courts. The primary approach among commentators is that the command to sanctify the priest is not merely a suggestion to show respect, but a practical directive requiring active intervention. If a priest enters into a forbidden marriage, such as marrying a divorced woman, the court is obligated to force him to divorce her, even employing physical coercion until he complies. While earlier instructions alluded to forcing compliance regarding ritual impurity from the dead, the focus here is specifically on preventing illicit marriages [מזרחי, שפתי חכמים, גור אריה]. Even if the marriage has already taken place and the priest appears to have forfeited his sacred status, the community cannot abandon him to his fallen state; they must compel him to rectify the situation [דברי דוד]. Furthermore, the public cannot ignore a single transgressing priest simply because there are plenty of other valid priests available to serve in the Temple. The sanctity of every individual matters [אור החיים].

This public responsibility stems from the priest's role in presenting offerings upon the altar. Because he is chosen to serve God directly, his elevated position requires strict maintenance of his sanctity [אבן עזרא, ביאור יש״ר]. Additionally, these offerings are conceptually linked to the nation's own sustenance. The priest acts as the conduit for national abundance. If he becomes unfit to stand before God, it jeopardizes the blessings and livelihood of the entire community. Thus, the public has a direct, vested interest in ensuring he remains holy [העמק דבר].

Beyond enforcing prohibitions, the community is commanded to actively honor the priest in daily life. He is to be given precedence in all matters, such as speaking first, being called first to the public Torah reading, leading the Grace after Meals, and receiving a prime portion at gatherings. Because this aspect involves personal honor rather than strict prohibitions, a priest is permitted to willingly waive these privileges and defer to others [פני דוד]. This required reverence is permanent. A priest retains his holy status and the associated respect even if he develops a physical blemish that disqualifies him from active Temple service [מלבי״ם, חזקוני, אדרת אליהו].

Ultimately, the requirement to sanctify the priesthood is directed at the entire nation because the priest's holiness is deeply intertwined with the people. His sacred status does not isolate him but serves as the very foundation for the nation's own sanctity. It is exclusively through the holiness of the priests that God rests His presence within the camp; without worthy priests, the Divine presence departs [רמב״ן, אור החיים, רש״ר הירש]. Honoring the priest is not an endorsement of personal arrogance, but an expression of reverence for God Himself. When the community honors God's servants, they honor their Creator. In return, God bestows honor and holiness upon the entire nation [אלשיך, העמק דבר].
