תְּהִלַּת ה' יְדַבֶּר פִּי, וִיבָרֵךְ כָּל בָּשָׂר שֵׁם קָדְשׁוֹ לְעוֹלָם וָעֶד
Tehillas Ado-nai y'daber pi, vivarech kol basar shem kodsho l'olam va'ed.
My mouth shall speak the praise of the Lord, and let all flesh bless His holy name forever and ever.
Good morning everyone. Welcome back to Learn to Daven - Day 76.
We're at the last verse of Ashrei. The whole chapter, the full aleph-beis, the climb up through "Potei'ach es yadecha" - and now David signs his name at the bottom. And look at how he closes it:
"Tehillas Hashem yedaber pi" - my mouth shall speak the praise of God. "Vivarech kol basar shem kodsho l'olam va'ed" - and all flesh shall bless His holy name forever and ever.
I want you to notice the two words sitting right next to each other, because the whole verse is hiding in the gap between them. The first half is pi - my mouth. Singular. One man. The most personal word there is. And then, half a breath later, the second half opens up to kol basar - all flesh. Every living thing. The whole world.
That's an enormous jump in one sentence. He starts with one mouth and ends with all of creation. And that's not an accident - that's the entire architecture of how praise works.
Here's the thing about that little word pi. Of everything David could have ended his greatest psalm with, he ends with the mouth. Why the mouth? The Chassidic seforim talk about this - that speech is the lowest of the soul's "garments," the most external thing a person does. Thought is inside you. Speech is the moment the inside finally comes out into the world. And David is telling you what that machine is for. What is the purpose of a human mouth? Not gossip, not complaining, not deal-making. Tehillas Hashem yedaber pi. The mouth exists to praise. That's its job description. Everything else is the mouth on its day off.
And now watch what happens once one mouth starts doing its job. Vivarech kol basar. The praise doesn't stay in the room. One person opens his mouth - and the whole world gets pulled into it.
I think most of us assume it works the other way around. We think: when everybody else is davening, when the whole shul is singing, then I'll get lifted into it. We wait for the crowd. But David writes it in the exact opposite order. First pi - you. One mouth, alone, maybe half-asleep, maybe the only one in the room who means it. And that is what tips the world. Then kol basar. The individual goes first. The universal follows.
You've felt this. You know what it's like to walk into a room where one person is genuinely, quietly grateful - not performing it, just living it - and somehow the whole room softens. One person who actually means the bracha changes the temperature of the whole table. That's Tehillas Hashem yedaber pi, vivarech kol basar. Your one mouth is not too small to matter. Your one mouth is where the whole thing starts.
And think about what a perfect seal this is for Ashrei. The whole chapter has been about God's open hand - Potei'ach es yadecha - God pouring out, God feeding, God catching the fallen, God near to all who call. Verse after verse of what God gives down to us. And the very last word David gives back is the only thing a human being actually owns: his mouth. God opens His hand; you open your mouth. That's the whole exchange. That's the deal.
So tomorrow, when you reach the end of Ashrei and you say Tehillas Hashem yedaber pi - don't mumble it as the part where you finally get to sit down. Say it like you mean it's your job. One mouth. Said with everything. And trust that David was right - that one honest mouth pulls the whole world up behind it.
Tomorrow, something strange. Because there's a letter missing from Ashrei. The whole aleph-beis is there - except one. We'll find the letter David refused to write, and why.
