"1In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple. 2Above 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. 3And one called to another and said: Holy, holy, holy is the Lord of hosts; the whole earth is full of his glory! 4And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke. 5And 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! 6Then one of the seraphim flew to me, having in his hand a burning coal that he had taken with tongs from the altar. 7And he touched my mouth and said: Behold, this has touched your lips; your guilt is taken away, and your sin atoned for. 8And I heard the voice of the Lord saying, Whom shall I send, and who will go for us? Then I said, Here I am! Send me. 9And he said, Go, and say to this people: Keep on hearing, but do not understand; keep on seeing, but do not perceive. 10 Make the heart of this people dull, and their ears heavy, and blind their eyes; lest they see with their eyes, and hear with their ears, and understand with their hearts, and turn and be healed. 11 Then I said, How long, O Lord? And he said: Until cities lie waste without inhabitant, and houses without people, and the land is a desolate waste, 12 and the Lord removes people far away, and the forsaken places are many in the midst of the land. 13 And though a tenth remain in it, it will be burned again, like a terebinth or an oak, whose stump remains when it is felled. The holy seed is its stump."
