Isaiah 6:1-7  Revised Standard Version Catholic Edition

A Vision of God in the Temple

6 ^[a]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. 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:

⁴ And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke. ⁵ 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!”

⁶ Then flew one of the seraphim to me, having in his hand a burning coal which he had taken with tongs from the altar. ⁷ And he touched my mouth, and said: “Behold, this has touched your lips; your guilt is taken away, and your sin forgiven.”
