As Sephardic Jews, we have the privilege of having the Kohanim bless the congregation each morning and on Shabbat and Yom Tob, twice. The Zohar states that the moment of Birkat Kohanim is an auspicious time for mercy and compassion. The Lev Eliyahu adds that one who is seeking a shidduch or to have children can hold out their open hands, as if ready to receive the blessing. On Friday nights we bless our children using this same text, and during the wedding ceremony the Kohanim use it to bless the bride and groom. The Gemara (Berachot 55b) also outlines a specific prayer one can recite during the blessing for a bad dream.
We may ask why the Kohanim are specifically chosen for this task rather than a Rabbi or other leader. The Gemara (Megillah 15a) tells us that even the blessing of a common person carries weight, so what makes the Kohanim uniquely suited? The Gemara (Sotah 40a) explains that it is the Kohen’s duality. That is, they are elevated through the Torah’s restrictions and with their kedusha, symbolizing a connection to Heaven, yet they live ordinary lives among the people. This is reflected in the ritual itself. Their raised hands reach toward Heaven for each blessing, while their removed shoes keep them grounded. They first face the Hechal, acknowledging that the blessing comes from G-d, then turn to the congregation to deliver it.
This brings us to the blessing itself. No mention of health, livelihood, happiness, or other specific blessings, though other texts in the Torah certainly address those. Just blessing, protection, grace, and peace. Perhaps because these are the foundations everything else rests on. Of all of them, the blessing saves the most essential for last: shalom (peace).
Peace is more underrated than we give it credit for. You can have every luxury imaginable, but a home without peace between husband and wife is a nightmare regardless. Money without peace of mind is just a well furnished headache. We have all heard of lottery winners whose lives fell apart after their windfall, only to realize they had something far more valuable before.
It is no coincidence that Aharon HaKohen was the embodiment of peace. Pirkei Abot (1:12) teaches us “to be among his students, to love peace and pursue it.” Note that it says obtain it first, then spread it. Only once you have experienced true peace and understand its worth, can you genuinely teach and spread its message. That is precisely why the blessing ends with shalom. It is not an afterthought. That is the whole point. Without peace, nothing else can endure.
