In the year that King Uzzi'ah died I saw the Lord sitting upon a throne, high and lifted up; and his train filled the temple.
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.
And one called to another and said: "Holy, holy, holy is the LORD of hosts; the whole earth is full of his glory."
And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke.
And I said: "Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the LORD of hosts!"
Then flew one of the seraphim to me, having in his hand a burning coal which he had taken with tongs from the altar.
And he touched my mouth, and said: "Behold, this has touched your lips; your guilt is taken away, and your sin forgiven."
And I heard the voice of the Lord saying, "Whom shall I send, and who will go for us?" Then I said, "Here am I! Send me."
