במדבר, פרק ו׳, פסוק כ״ג

The act of bestowing the priestly blessing is far more than a simple expression of goodwill. It is a profound act of holy service, functioning as a direct conduit for Divine abundance to flow to the people. The primary approach among commentators is that the priests themselves are not the source of this blessing, nor do they possess an independent power to bless. Rather, they serve as dedicated vessels and messengers of prayer, while God remains the true and ultimate source of the blessing [רשב״ם, אברבנאל, רש״ר הירש, נחלת יעקב]. This transmission is designed to bypass strict judgment, swiftly drawing down kindness and mercy upon the Israelites without delay [חומש קה״ת].

The placement of this Commandment within the broader narrative is highly intentional. Occurring immediately after the laws of the Nazirite, who abstains from wine, it teaches that a priest must be completely sober when delivering the blessing [הטור הארוך, תורה תמימה, כלי יקר, חזקוני]. Furthermore, its introduction right after the organization of the Israelite camp and just before their journeys and battles serves to provide the nation with both spiritual and physical protection [צרור המור].

Delivering this blessing is not a voluntary act left to the priests' discretion. It is an absolute, ongoing positive Commandment for all generations. This royal decree highlights the elevated status of the priests [אור החיים, רמב״ן]. The instructions demand strict adherence to a specific form that cannot be altered. The blessing must be recited exactly as prescribed: in the holy tongue, while standing, and with hands raised upward to indicate that God is the source of the bounty [רלב״ג, תורה תמימה, רש״ר הירש, שפתי כהן]. It must also be delivered face-to-face, reflecting deep respect, love, and a sense of awe toward the congregation [תורה תמימה, חתם סופר].

The obligation to bless the people is continuous and permanent [רש״י, מזרחי, גור אריה]. The delivery must never be rushed or panicked; rather, the priests must perform the service with deep intention and a whole heart [רש״י, רבינו בחיי]. The blessing must be spoken in a clear, moderate voice, similar to a person talking to a friend, ensuring that the entire congregation, including women and converts, can hear it perfectly [רש״י, תורה תמימה, צפנת פענח].

A fundamental rule of this service is that the priests do not initiate the blessing on their own. The leader of the congregation must read the words to them first, and the priests repeat them word for word. This sequence ensures that the priest is initially filled with Divine blessing from God, allowing him to then pour it outward to the people like an overflowing vessel [רבינו בחיי, רש״ר הירש, כלי יקר, העמק דבר]. Because of this requirement to be prompted, a priest only violates the Commandment if he is explicitly called upon to bless and refuses [פענח רזא, בכור שור, חזקוני].

Because this act is a formal holy service, it demands proper preparation and a state of personal wholeness. The priest must wash his hands before beginning. Additionally, some commentators note that the priest should be married. The reasoning is that an individual without a spouse exists in a state lacking complete blessing, and one who is not fully blessed himself cannot successfully transmit God's blessing to others [רבינו בחיי, שפתי כהן].
