There is a small halachic detail in the Shacharit prayer—specifically in the blessings before Kriyat Shema—that can easily be overlooked.
When we recite Yotzer Or U’vorei Choshech, we eventually reach the familiar words, “Kadosh, Kadosh, Kadosh...” and “Baruch kevod Hashem mimkomo.” These verses reflect the celestial praises of the angels. If you look carefully at many modern siddurim, you'll find a note: “If you're standing, sit down for these verses.”
Why? Why the deliberate change in posture?
The reason is to distinguish between these verses—said during the blessings of Kriyat Shema—and the nearly identical ones said later during the Chazarat HaShatz in the repetition of the Amidah, during the section known as Kedusha (see Orach Chaim 53; Mishnah Berurah ibid. 12, Kaf HaChaim ibid. 20).
But there's something much deeper at play here.
The angels in Heaven—the malachim—chant these praises constantly: “Kadosh, Kadosh, Kadosh Hashem Tzevakot...” and “Baruch kevod Hashem mimkomo.” But the Gemara (Chullin 91b) teaches something astonishing: the angels are not permitted to say these praises until we, down here on Earth, recite them first (see Nefesh HaChaim 1:6).
Think about that for a moment. The billions of celestial beings whose entire existence is to glorify Hashem—are silent. Silent. Until we initiate the praise down here.
When we say “Kadosh, Kadosh, Kadosh” during Yotzer Or, we are not actively praising; we are recounting the praises the angels give. But when we stand during Kedusha and say “Kadosh, Kadosh, Kadosh,” that is our direct praise. And when we do that, we trigger the angels above to join in. That is why the Halacha instructs us to sit during the earlier version—to signal: This is not yet the real moment. The real impact comes later, when we stand and declare it ourselves. And it's not only these words.
Every mitzvah we do, every act of kindness, every moment of connection to Hashem—no matter how small it may seem to us—can reverberate across spiritual realms. So the next time you whisper “Kadosh, Kadosh, Kadosh,” pause. Realize the angels are listening. They are waiting. And they will not move until you do.
You’re not just reciting ancient words. You’re leading the Heavenly chorus.
