Isaiah 6:6-8

Wycliffe Bible

⁶ And one of [the] seraphim flew to me, and a burning coal was in his hand, which coal he had taken with a (pair of) tong(s) from the altar.

⁷ And he touched my mouth, and said, Lo! I have touched thy lips with this coal, and thy wickedness shall be done away, and thy sin shall be cleansed.

⁸ And I heard the voice of the Lord, saying, Whom shall I send, and who shall go to you? And I said, Lo! I; send thou me.
