Isaiah 6:4–9

And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke. And I said: “Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts!”

Then one of the seraphim flew to me, having in his hand a burning coal that he had taken with tongs from the altar. And he touched my mouth and said: “Behold, this has touched your lips; your guilt is taken away, and your sin atoned for.”

And I heard the voice of the Lord saying, “Whom shall I send, and who will go for us?” Then I said, “Here I am! Send me.” And he said, “Go, and say to this people:

“ ‘Keep on hearing, but do not understand;

keep on seeing, but do not perceive.’

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

“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. With it he touched my mouth and said, “See, this has touched your lips; your guilt is taken away and your sin atoned for.”

Then 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!”

He said, “Go and tell this people:

“ ‘Be ever hearing, but never understanding;

be ever seeing, but never perceiving.’

Their voices shook the Temple to its foundations, and the entire building was filled with smoke.

Then I said, “It’s all over! I am doomed, for I am a sinful man. I have filthy lips, and I live among a people with filthy lips. Yet I have seen the King, the Lord of Heaven’s Armies.”

Then one of the seraphim flew to me with a burning coal he had taken from the altar with a pair of tongs. He touched my lips with it and said, “See, this coal has touched your lips. Now your guilt is removed, and your sins are forgiven.”

Then I heard the Lord asking, “Whom should I send as a messenger to this people? Who will go for us?”

I said, “Here I am. Send me.”

And he said, “Yes, go, and say to this people,

‘Listen carefully, but do not understand.

Watch closely, but learn nothing.’

And the pivots of the thresholds shook from the sound of those who called, and the house was filled with smoke.

And I said, “Woe to me! For I am destroyed! For I am a man of unclean lips, and I am living among a people of unclean lips, for my eyes have seen the king, Yahweh of hosts!”

Then one of the seraphs flew to me, and in his hand was a hot coal he had taken from the altar with tongs.

And he touched my mouth, and he said,

“Look! This has touched your lips

and has removed your guilt,

and your sin is annulled.”

Then I heard the voice of the Lord saying,

“Whom shall I send?

And who will go for us?”

And I said,

“I am here!

Send me!”

And he said, “Go and say to this people,

‘Keep on listening and do not comprehend!

And keep on looking and do not understand!’

And the posts of the door moved at the voice of him that cried, and the house was filled with smoke. Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the Lord of hosts. Then flew one of the seraphims unto me, having a live coal in his hand, which he had taken with the tongs from off the altar: And he laid it upon my mouth, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin purged. Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me. And he said, Go, and tell this people,

Hear ye indeed, but understand not;

And see ye indeed, but perceive not.
