Isaiah 6:1-4

1In the year that King Uzziah died, I saw the Lord, high and exalted, seated on a throne; and the train of his robe filled the temple. 2Above him were seraphim, each with six wings: With two wings they covered their faces, with two they covered their feet, and with two they were flying. 3And they were calling to one another: “Holy, holy, holy is the Lord Almighty; the whole earth is full of his glory.” 4At the sound of their voices the doorposts and thresholds shook and the temple was filled with smoke.
