In the year of King Uzziah’s death I saw the Lord of Hosts seated on a high throne; his train filled the sanctuary; above him stood seraphs, each one with six wings: two to cover its face, two to cover its feet, and two for flying.

And they cried out to one another in this way,

‘Holy, holy, holy is the Lord of Hosts.
His glory fills the whole earth.’

The foundations of the threshold shook with the voice of the one who cried out, and the Temple was filled with smoke. I said:

‘What a wretched state I am in! I am lost,
for I am a man of unclean lips
and I live among a people of unclean lips,
and my eyes have looked at the King, the Lord of Hosts.’

Then one of the seraphs flew to me, holding in his hand a live coal which he had taken from the altar with a pair of tongs. With this he touched my mouth and said:

‘See now, this has touched your lips,
your sin is taken away,
your iniquity is purged.’

Then I heard the voice of the Lord saying:

‘Whom shall I send? Who will be our messenger?’
I answered, ‘Here I am, send me.’

Here I am, Lord! I come to do your will.

I waited, I waited for the Lord
  and he stooped down to me;
  he heard my cry.

Here I am, Lord! I come to do your will.

He put a new song into my mouth,
  praise of our God.
Many shall see and fear
  and shall trust in the Lord.

Here I am, Lord! I come to do your will.

You do not ask for sacrifice and offerings,
  but an open ear.
You do not ask for holocaust and victim.
  Instead, here am I.

Here I am, Lord! I come to do your will.

In the scroll of the book it stands written
  that I should do your will.
My God, I delight in your law
  in the depth of my heart.

Here I am, Lord! I come to do your will.

Your justice I have proclaimed
  in the great assembly.
My lips I have not sealed;
  you know it, O Lord.

Here I am, Lord! I come to do your will.

Alleluia, alleluia!
Jesus proclaimed the Good News of the kingdom
and cured all kinds of sickness among the people.
Alleluia!
