(22) The Eternal spoke to Moses: (23) Speak to Aaron and his sons: Thus shall you bless the people of Israel. Say to them:
(24) The Eternal bless you and protect you!
(25) The Eternal deal kindly and graciously with you!
(26) The Eternal bestow favour upon you and grant you peace!
(27) Thus they shall link My name with the people of Israel, and I, I will bless them.
I love that scene in the original 1961 movie "Parent Trap" when Susan (played by Hayley Mills) hugs her grandfather, sniffing his collar, refusing to let go.
When her grandfather asks what she’s doing, she responds:
“I’m making a memory. Someday when I’m quite grown up I’ll remember my grandfather, and how he smelled of peppermint and pipe tobacco.”
“I must only think of the Magic.” It all seemed most majestic and mysterious when they sat down in their circle. Ben Weatherstaff felt as if he had somehow been led into appearing at a prayer-meeting. Ordinarily he was very fixed in being what he called “agen’ prayer-meetin’s” but this being the Rajah’s affair he did not resent it and was indeed inclined to be gratified at being called upon to assist. Mistress Mary felt solemnly enraptured. Dickon held his rabbit in his arm, and perhaps he made some charmer’s signal no one heard, for when he sat down, cross-legged like the rest, the crow, the fox, the squirrels and the lamb slowly drew near and made part of the circle, settling each into a place of rest as if of their own desire.
“The ‘creatures’ have come,” said Colin gravely. “They want to help us.”
Colin really looked quite beautiful, Mary thought. He held his head high as if he felt like a sort of priest and his strange eyes had a wonderful look in them. The light shone on him through the tree canopy.
“Now we will begin,” he said. “Shall we sway backward and forward, Mary, as if we were dervishes?”
“I canna’ do no swayin’ back’ard and for’ard,” said Ben Weatherstaff. “I’ve got th’ rheumatics.”
“The Magic will take them away,” said Colin in a High Priest tone, “but we won’t sway until it has done it. We will only chant.”
“I canna’ do no chantin’” said Ben Weatherstaff a trifle testily. “They turned me out o’ th’ church choir th’ only time I ever tried it.”
No one smiled. They were all too much in earnest. Colin’s face was not even crossed by a shadow. He was thinking only of the Magic.
“Then I will chant,” he said. And he began, looking like a strange boy spirit. “The sun is shining—the sun is shining. That is the Magic. The flowers are growing—the roots are stirring. That is the Magic. Being alive is the Magic—being strong is the Magic. The Magic is in me—the Magic is in me. It is in me—it is in me. It’s in every one of us. It’s in Ben Weatherstaff’s back. Magic! Magic! Come and help!”
He said it a great many times—not a thousand times but quite a goodly number. Mary listened entranced. She felt as if it were at once queer and beautiful and she wanted him to go on and on. Ben Weatherstaff began to feel soothed into a sort of dream which was quite agreeable. The humming of the bees in the blossoms mingled with the chanting voice and drowsily melted into a doze. Dickon sat cross-legged with his rabbit asleep on his arm and a hand resting on the lamb’s back. Soot had pushed away a squirrel and huddled close to him on his shoulder, the gray film dropped over his eyes. At last Colin stopped.
“Now I am going to walk round the garden,” he announced.
from The Secret Garden, by Francis Hodgson Burnett CHAPTER 23 "Magic"
the blessing of physical protection, through the blessing of spiritual shelter, to the blessing of shalom – wholeness, completion or peace.
Studies in Bemidbar, Nehama Leibowitz, p. 67
(1) יברכך [THE LORD] BLESS THEE — that thy property may increase (Sifrei Bamidbar 40). (2) וישמרך AND MAY HE GUARD THEE — that no robbers come upon thee to take away thy property. For a human being who gives a present to his servant cannot guard him against everybody, and if a band of robbers attack him and take it away, what pleasure can he, then, derive from this present?! The Holy One, blessed be He, however, both gives and guards — against everybody (Midrash Tanchuma, Nasso 10).
This in fact reflects an important theological point: namely, that the priests are not able to give blessing of their own accord. Rather, they serve as intermediaries, vessels of the Divine spirit, delivered by means of their reciting these words. At the time of blessing their own individual personality is, so to speak, obscured by their priestly function. Hence they hide their faces. The lesson taught is ultimately one of humility.
The Netziv's explanation of "and protect you" goes further:. "May God protect you, lest the very blessing you receive turn into a stumbling block." The blessing of wealth, for example, can lead to greed, or stinginess, or lack of empathy. Or it can lead to a perpetual state of anxiety that one does not have enough or that one may lose what one has earned Crucially, the Netziv points out, even the blessing of Torah learning can yield rotten fruit: The Torah scholar can easily become arrogant or cause a desecration of God's name.
Two questions emerge from this formula: First, why do the priests talk about being sanctified with the sanctity of Aaron instead of employing the usual formula, "who has sanctified us with God's commandments"? And second, why the mention of love at the end of the blessing?
The answer to our two questions is identical: Blessing depends on love. The Torah does not assign the priests the task of rote recitation. On the contrary, it calls upon them to love the people. Indeed, the Zohar declares that "a priest who does not love the people or is not loved by the people should not raise his hands to bless them" (Naso, 147b). Aaron, the first priest, is remembered as "a lover of peace and a pursuer of peace, one who love[d] people and brought them closer to Torah" (Mishnah, Avot 1:12). "The holiness of Aaron," says R. Shalom Noah Berezovsky (1911-2000), "flowed from his love." A priest devoid of love is a priest in name only.
By doing this the Rebbe was offering him a lesson, that when you offer a prayer to bring down a blessing it requires a postal address, don't do it just as a routine - keep specific people in mind. Bring down blessings for them.
He was, also, I think, showing Reb Zalman his own love by showing that he recognized him and also his important role as a Cohen.
In Midrash Tanhuma the people of Israel question the role of the priests in the blessing, saying to God: "We only need Your blessing." God responds, "I will stand with the priests and bless you."
In Ashkenazi Diaspora it is done at mussaf of festival days.
The formulation of the mitzvah of Birkat Cohanim shows it is a mitzva De'oraita - a positive mitzvah from the Torah for the Cohanim to bless the Jewish People every day. This is how it is codified by the Sefer HaHinuch. So how did the custom of not doing Birkat Cohanim daily start in the Diaspora?
reasons given include:
The custom was to immerse in a mikveh before doing Birkat Cohanim. This was very hard to do in the Winter in Eastern Europe so they stopped doing it every day.
Rabbi Moshe Isserles wrote that "It has become the practice that the Cohanim do not raise their hands in blessing except on Yom Tov, as then they are in a state of happiness because of Yom Tov and a person who is in good spirits should administer the blessing. They are not in a state of happiness on other days even on Shabbatot as they are preoccupied with thoughts concerning their sustenance and over the cessation of their work. Even on Yom Tov they only do it at Musaf as then they are about to leave synagogue and rejoice in the celebration of Yom Tov."
Sephardi communities in diaspora also vary about when they do it - only days torah is read/ only shabbat/ every day/ only yom tov.....
The Birkat Cohanim/Nesiyat Cappayim is therefore not given in Progressive liturgy in the way that the orthodox world does it. However the words of the prayer are powerful and meaningful, so this blessing is often given by the service leader at the end of the service, and in other liturgical contexts.
An archaeological find in a burial chamber in Ketef Hinnom (South of the Old City of Jerusalem) in 1979 shows that this blessing goes at least as far back as the 7th century BCE when the 1st Temple still stood and before the Babylonian exile.
Two tiny folded silver scrolls with different versions of this blessing and some other fragments of verses were discovered, each including the words “May YHWH bless you and guard you; may YHWH make his face shine upon you.”
This is the oldest text ever found, that occurs in the Hebrew Bible.
The scrolls must have been used as amulets by ancient Israelites more than 2,600 years ago.
