Isaiah 6:5-7

Douay-Rheims 1899 American Edition

⁵ And I said: Woe is me, because I have held my peace; because I am a man of unclean lips, and I dwell in the midst of a people that hath unclean lips, and I have seen with my eyes the King the Lord of hosts.

⁶ And one of the seraphims flew to me, and in his hand was a live coal, which he had taken with the tongs off the altar.

⁷ And he touched my mouth, and said: Behold this hath touched thy lips, and thy iniquities shall be taken away, and thy sin shall be cleansed.
