Isaiah 6:6-8

Amplified Bible, Classic Edition

⁶ Then flew one of the seraphim [heavenly beings] to me, having a live coal in his hand which he had taken with tongs from off the altar;

⁷ And with it he touched my mouth and said, Behold, this has touched your lips; your iniquity and guilt are taken away, and your sin is completely atoned for and forgiven.

⁸ Also I heard the voice of the Lord, saying, Whom shall I send? And who will go for Us? Then said I, Here am I; send me.
