Isaiah 6:6-8 Holman Christian Standard Bible (HCSB)
6 Then one of the seraphim flew to me, and in his hand was a glowing coal that he had taken from the altar with tongs. 7 He touched my mouth with it and said:
Now that this has touched your lips,
8 Then I heard the voice of the Lord saying:
Who should I send?
Here I am. Send me.
