Isaiah 6:3-6 New International Version (NIV)

3. And they were calling to one another: “Holy, holy, holy is the Lord Almighty; the whole earth is full of his glory.”

4. At the sound of their voices the doorposts and thresholds shook and the temple was filled with smoke.

5. “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.”

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.
