Isaiah 6:1-9

1In the year that King Uzziah died, I saw the Lord seated on a high and lofty throne, and the hem of his robe filled the temple.

2Seraphim were standing above him; they each had six wings: with two they covered their faces, with two they covered their feet, and with two they flew.

3And one called to another: Holy, holy, holy is the Lord of Armies; his glory fills the whole earth.

4The foundations of the doorways shook at the sound of their voices, and the temple was filled with smoke.

5Then I said: Woe is me for I am ruined because I am a man of unclean lips and live among a people of unclean lips, and because my eyes have seen the King, the Lord of Armies.

6Then one of the seraphim flew to me, and in his hand was a glowing coal that he had taken from the altar with tongs.

7He touched my mouth with it and said: Now that this has touched your lips, your iniquity is removed and your sin is atoned for.

8Then I heard the voice of the Lord asking: Who will I send? Who will go for us? I said: Here I am. Send me.

9And he replied: Go! Say to these people: Keep listening, but do not understand; keep looking, but do not perceive.
