In the year of King Uzziah's death I saw the Lord seated on a throne, high and exalted, and the skirt of his robe filled the temple . About him were attendant Seraphim ...
And, as each One called, the threshold shook to its foundations, while the house was filled with smoke. Then I cried, Woe is me! I am lost, for I am a man of unclean lips and I dwell among a people of unclean lips; yet with these eyes I have seen the King, the Lord of Hosts.
Then one of the seraphims flew to me carrying in his hand a glowing coal which he had taken from the altar with a pair of tongs - He touched my mouth with it and said, See, this has touched your lips; Your iniquity is removed, and Your sin is wiped away.
Then I heard the Lord saying, Whom shall I send? Who will go for me? And I answered, Here am I; send me. He said, Go and tell this people: You listen and listen, but you will not understand. You may look and look again, but you will never know.
