Holy, Holy, Holy Are You Lord

Isaiah's Vision of the Lord
6 In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train[a] of his robe filled the temple. 2 Above him stood the seraphim. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew. 3 And one called to another and said:

“Holy, holy, holy is the Lord of hosts;
the whole earth is full of his glory!”
