Isaiah 6:6-8

Revised Standard Version

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.” ⁸ 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.”
