Isaiah 6:6-8

New International Version - UK

⁶ Then one of the seraphim flew to me with a live coal in his hand, which he had taken with tongs from the altar. ⁷ With it he touched my mouth and said, ‘See, this has touched your lips; your guilt is taken away and your sin atoned for.’

⁸ Then I heard the voice of the Lord saying, ‘Whom shall I send? And who will go for us?’

And I said, ‘Here am I. Send me!’
