Isaiah 6:6-7

New American Standard Bible

⁶ Then one of the seraphim flew to me with a burning coal in his hand, which he had taken from the ^(A)altar with tongs. ⁷ He ^(B)touched my mouth with it and said, “Behold, this has touched your lips; and ^(C)your guilt is taken away and atonement is made for your sin.”
