1In the year that King Uzziah died, I saw the Lord, high and exalted, seated on a throne; and the train of his robe filled the temple. 2Above him were seraphim, each with six wings: With two wings they covered their faces, with two they covered their feet, and with two they were flying. 3And they were calling to one another:

“Holy, holy, holy is the Lord Almighty;
the whole earth is full of his glory.”
4At 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.”

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

8Then 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!”

9He said, “Go and tell this people:

“ ‘Be ever hearing, but never understanding;
be ever seeing, but never perceiving.’
10Make the heart of this people calloused;
make their ears dull
and close their eyes.a
Otherwise they might see with their eyes,
hear with their ears,
understand with their hearts,
and turn and be healed.”
Isaiah 6:1-10
