The Lord says this:

But you, Bethlehem Ephrathah, 
the least of the clans of Judah,
out of you will be born for me 
the one who is to rule over Israel;
his origin goes back to the distant past, 
to the days of old.
The Lord is therefore going to abandon them
till the time when she who is to give birth gives birth.
Then the remnant of his brothers will come back
to the sons of Israel.
He will stand and feed his flock 
with the power of the Lord,
with the majesty of the name of his God.
They will live secure, for from then on he will extend his power
to the ends of the land.
He himself will be peace.

Lord of hosts, bring us back; let your face shine on us and we shall be saved.

O shepherd of Israel, hear us,
  shine forth from your cherubim throne.
O Lord, rouse up your might,
  O Lord, come to our help.

Lord of hosts, bring us back; let your face shine on us and we shall be saved.

God of hosts, turn again, we implore,
  look down from heaven and see.
Visit this vine and protect it,
  the vine your right hand has planted.

Lord of hosts, bring us back; let your face shine on us and we shall be saved.

May your hand be on the man you have chosen,
  the man you have given your strength.
And we shall never forsake you again;
  give us life that we may call upon your name.

Lord of hosts, bring us back; let your face shine on us and we shall be saved.

This is what Christ said, on coming into the world:

You who wanted no sacrifice or oblation, 
prepared a body for me.
You took no pleasure in holocausts or sacrifices for sin;
then I said, 
just as I was commanded in the scroll of the book,
‘God, here I am! I am coming to obey your will.’

Notice that he says first: You did not want what the Law lays down as the things to be offered, that is: the sacrifices, the oblations, the holocausts and the sacrifices for sin, and you took no pleasure in them; and then he says: Here I am! I am coming to obey your will. He is abolishing the first sort to replace it with the second. And this will was for us to be made holy by the offering of his body made once and for all by Jesus Christ.

Alleluia, alleluia!
I am the handmaid of the Lord:
let what you have said be done to me.
Alleluia!
