"My Soul Magnifies the Lord" (The Magnificat) from Evening Prayer, LSB 248. This is also known as the Song of Mary from Luke 1:46-55.
My soul magnifies the Lord,
and my spirit rejoices in God, my Savior;
For He has regarded
the lowliness of His handmaiden.
For behold, from this day
all generations will call me blessed.
For the Mighty One has done great things to me,
and holy is His name;
And His mercy is on those who fear Him
from generation to generation.
He has shown strength with his arm;
He has scattered the proud in the imagination of their hearts.
He has cast down the mighty from their thrones
and has exalted the lowly.
He has filled the hungry with good things,
and the rich He has sent empty away.
He has helped his servant Israel in remembrance of his mercy
as He spoke to our fathers, to Abraham and to his seed forever.
