Alleluia, alleluia, alleluia.
new work [bad word] on hand
Through might and grace of God's messenger,
To save the lost of every land.
For he is now free who was once in bondage;
We may well sing, alleluia!
By Gabriel it was begun;
just as the sun shone through the glass,
Jesus Christ was conceived
of Mary, mother full of grace.
Now sing we here, alleluia!
Now is fulfilled the prophecy
of David and of Jeremiah,
and also of Isaiah.
Sing we therefore, both loud and high,
alleluia, alleluia!
Alleluia, this sweet song,
out of a green branch has [bad word] 
God send us the life that lasts long;
Now joy and bliss be among
those who thus can sing, alleluia.
