The cry "And one cried to the other and said: Holy, holy, holy, Lord of Hosts, the whole earth is full of his glory" is the angelic proclamation from the vision of Isaiah (Isaiah 6:3), a threefold sanctification that reverberates through the Hekhalot and Merkabah mystical traditions. The phrase, known in Hebrew as the Kedushah, is uttered by the Seraphim who stand above the throne of God, each with six wings, covering their faces and feet in awe while flying. Its translation from the Masoretic Text emphasizes the immanence of divine glory filling the material world, a paradox of transcendence and presence.

Position on the Tree of Life

This utterance corresponds to Sephirah 9, Yesod (Foundation), on the Tree of Life. Yesod is the sphere of the astral plane, the receptacle of all forces from above, and the gateway through which the divine glory descends into Malkuth. The angelic function here is to stabilize and transmit the sanctifying power of the Kedushah into the physical world, making the whole earth full of His glory a realized state.

Astrological and planetary correspondence

Yesod is governed by the Moon, reflecting the reflective, receptive, and cyclical nature of this angelic cry. The Moon’s phases mirror the perpetual repetition of the Kedushah—a continuous, rhythmic sanctification that never ceases, just as the lunar cycle renews itself. The phrase thus aligns with the lunar current of hidden light and the foundation of all manifestation.

Historical context

The Kedushah is central to Jewish liturgy, recited in the Amidah prayer and the Yotzer Ohr blessing, and is echoed in the Christian Sanctus of the Mass. In the Hekhalot literature, this cry is the key that opens the seventh palace, where the angelic hosts chant it in unison before the throne. The Zohar interprets the three "holy"s as corresponding to the three upper Sephiroth (Keter, Chokmah, Binah) or the three Patriarchs, while the final clause relates to the Shekhinah in Malkuth. In the 777 system, this phrase appears at step 9 (Yesod) in the column of Angelic Functions of Yetzirah, where it serves as the foundation for the entire angelic hierarchy’s praise. The repetition of the cry at multiple Sephiroth (Keter through Binah, and again at Yesod) indicates a descent of sanctity from the highest unity to the lowest foundation, where the glory becomes fully immanent.

In Liber 777, this phrase is the angelic function assigned to Yesod, linking the foundation of the Tree to the prophetic vision of Isaiah. It stands as the culmination of the six-winged Seraphim’s praise, a direct channel from the divine throne to the earth, ensuring that the whole earth is indeed full of His glory.
