Context
1 In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lifted up; and his train filled the temple.
2 Above him stood the seraphim. Each one had six wings. With two he covered his face. With two he covered his feet. With two he flew.
3 One called to another, and said, “Holy, holy, holy, is the LORD of Armies! The whole earth is full of his glory!”
