Benedictus Dominus Deus or Canticle of Zechariah.
Blessed be the Lord, the God of Israel;
he has come to his people and set them free.
He has raised up for us a mighty savior,
born of the house of his servant David.
Through his holy prophets he promised of old
that he would save us from our enemies,
from the hand of all who hate us.
He Promised to show mercy to our fathers
and to remember his holy covenant.
This was the oath he swore to out father Abraham:
to set us free from the hands of our enemies,
free to worship him without fear,
holy and righteous in his sight
all the days of our life.
You, my child, shall be called the prophet
of the Most High;
for you will go before the Lord to prepare his way,
to give his people knowledge of salvation
by the forgiveness of their sins.
In the tender compassion of our God
the dawn from on high shall break upon us,
to shine on those who dwell in darkness
and the shadow of death,
and to guide our feet into the way of peace.
Glory to the Father, and to the Son,
and to the Holy Spirit,
and it was in the beginning, is now,
and will be for ever. Amen.
