What seems like a simple act is actually steeped in tradition, detail, and a whole lot of meaning. Let's unpack it.

The Book of Numbers, Bamidbar in Hebrew, gives us the source for the Priestly Blessing. In Numbers 6:22-23, we read, "And the L-rd spoke to Moses, saying: Speak to Aaron and to his sons, saying: Thus shall you bless, etc." So, why all the emphasis on "saying?" Well, Sifrei Bamidbar, a collection of legal midrash, points out that because this whole section deals with Kohanim, with priests, Aaron and his sons are brought into the context of "saying" (dibbur). There’s a rule: when the dibbur, the divine communication, is to the Kohanim, the action belongs to them. When it’s to all of Israel, the action is for all of Israel. And if it’s for all of humankind, then even proselytes are included. It's all about who the message is intended for.

Now, what language are we talking about here? "Thus shall you bless the children of Israel" – in the holy tongue, Hebrew. You might ask, "But why not any language?" Clever question! The text anticipates this. Deuteronomy 27:12 says, "These shall stand to bless the people." Just as there, the blessing is in the holy tongue, so here, it must be too. Rabbi Yehudah offers another perspective: wherever you see words like aniyah ("answering"), amirah ("saying"), or cachah ("thus"), you know the holy tongue is intended.

And how should the Kohanim be positioned? Standing! "Thus shall you bless the children of Israel" – standing. Sounds obvious, right? But the text pushes us: maybe they can sit or kneel? Again, Deuteronomy 27:12 comes to the rescue: "These shall stand to bless the people." We see "blessing" mentioned in both places. Just as "blessing" there means standing, so too does "blessing" here. Rabbi Nathan adds something interesting. He points to Deuteronomy 10:8, which speaks of the Kohanim standing before the L-rd to minister and bless His name. Blessing, he says, is likened to ministering. And just as ministering requires standing, so does blessing.

Then comes the raising of hands. "Thus shall you bless the children of Israel" – with raised hands. You guessed it, the text anticipates our skepticism. Maybe they can keep their hands down? Leviticus 9:22 describes Aaron lifting his hands to the people as he blessed them. So, just as there were raised hands, so too here. But Rabbi Yonatan challenges this: maybe we need everything that was present there – Rosh Chodesh (new moon), a specific offering, and the High Priest? That seems a bit much! So, Deuteronomy 18:5 clarifies that a Cohein is chosen "to stand and minister in the name of the L-rd, he and his sons all of the days." So his sons are likened to him. Just as he raises his hands, so do his sons.

What about the Name itself? "Thus shall you bless the children of Israel" – with the explicit name, the Tetragrammaton, yod-keh-vav-keh. You might wonder, can they use a substitute name? Nope. It is written in Numbers 6:27, "And they shall place My name on the children of Israel" – the name that is distinctive with Me. But does this apply everywhere? Not quite. We also read in I Kings 11:36, "to place My name there." Just as there refers to the Temple, so too does this verse. In the Temple, the Tetragrammaton is used. Outside, an epithet suffices. These are the words of Rabbi Yoshiyah. Rabbi Yonatan offers another interpretation. He inverts Exodus 20:21, reading it as "Wherever I am revealed to you, there shall you mention My name." And where is God revealed? In the Temple! This is why, the text tells us, it is forbidden to utter the explicit Name outside the Temple borders.

Who gets the blessing? "Thus shall you bless the children of Israel" – this initially tells us only about the men of Israel. But what about women, proselytes, and servants? The phrase "Say to them" includes absolutely everyone. And what about the Kohanim themselves? Do they get blessed? Yes! Verse 27 says, "and I shall bless them (the Kohanim)."

"Thus shall you bless the children of Israel" – face to face. This means a direct, unobstructed view. Not back to face! The text reinforces this with "Say to them" – as one speaks to a neighbor, directly. And finally, the blessing must be spoken in a loud voice, so the whole congregation can hear. Not a whisper! The phrase "Say to them" implies that the entire community should be able to hear the blessing being said. And where does the prayer leader come in? The phrase "Say to them" also teaches us that the prayer leader prompts the Kohanim to give the blessing.

So, the next time you hear the Priestly Blessing, remember all the layers of meaning packed into those ancient words. It's not just a nice sentiment; it's a carefully constructed, deeply meaningful act, connecting us to generations past and to the divine presence. And maybe, just maybe, that connection is exactly what makes it so powerful.
