My soul magnifies the Lord,
and my spirit rejoices in God my Savior,
for he has looked on the humble estate of his servant.
For behold, from now on all generations will call me blessed;
for he who is mighty has done great things for me,
and holy is his name.
And his mercy is for those who fear him
from generation to generation.
He has shown strength with his arm;
he has scattered the proud in the thoughts of their hearts;
he has brought down the mighty from their thrones
and exalted those of humble estate;
he has filled the hungry with good things,
and the rich he has sent away empty.
He has helped his servant Israel,
in remembrance of his mercy,
as he spoke to our fathers,
to Abraham and to his offspring forever.
Glory be to the Father, and to the Son, and to the Holy Spirit:
as it was in the beginning, is now, and will be forever. Amen.

The Magnificat has been set music many times. Johann Sebastian Bach adapted that chant and wrote a cantata based on it.
Bach also wrote a major choral setting of the Magnificat:
The Magnificat is also a favorite text to be adapted / versified into the form of a hymn. Here is “Holy Is Your Name” with an anonymous text set to the Scottish folk tune “Wild Mountain Thyme.”
