Then I (Isaiah) said, "Woe is me, I am doomed! For
I am a man of unclean lips, living among a people of
unclean lips; yet my eyes have seen the King, the Lord
of hosts!" Then one of the seraphim flew to me, holding
an ember which he had taken with tongs from the altar.
He touched my mouth with it. "See," he said, "now that
this has touched your lips, your wickedness is removed,
your sin purged."
