Isaiah 6:5-6
Isaiah 6:5-6 NIV
“Woe to me!” I cried. “I am ruined! For I am a man of unclean lips, and I live among a people of unclean lips, and my eyes have seen the King, the LORD Almighty.” Then one of the seraphim flew to me with a live coal in his hand, which he had taken with tongs from the altar.
