Yeshayah 6:1-2

Orthodox Jewish Bible

6 In the year that the Melech Uziyah died, I saw Adonoi sitting upon a kisse, high and lifted up, and His robe filled the Heikhal.

² Above Him stood ministering the [flaming] seraphim; each one had six wings: with two he covered his face, with two he covered his feet, and with two he did fly.
