From Wikipedia, "Magnificat":
"The Magnificat (Latin: [My soul] magnifies) — also known as the Song of Mary or the Canticle of Mary — is a canticle frequently sung (or spoken) liturgically in Christian church services. It is one of the eight most ancient Christian hymns and perhaps the earliest Marian hymn. Its name comes from the first word of the Latin version of the canticle's text.
The text of the canticle is taken directly from the Gospel of Luke (Luke 1:46-55) where it is spoken by the Virgin Mary upon the occasion of her Visitation to her cousin Elizabeth. In the narrative, after Mary greets Elizabeth, who is pregnant with the future John the Baptist, the child moves within Elizabeth's womb. When Elizabeth praises Mary for her faith, Mary sings what is now known as the Magnificat in response."

Latin (older form):
Magnificat: anima mea Dominum.
Et exultavit spiritus meus: in Deo salutari meo.
Quia respexit humilitatem ancillae suae:
ecce enim ex hoc beatam me dicent omnes generationes.
Quia fecit mihi magna, qui potens est:
et sanctum nomen eius.
Et misericordia eius, a progenie et progenies:
Fecit potentiam in brachio suo:
dispersit superbos mente cordis sui.
Deposuit potentes de sede:
et exaltavit humiles.
Esurientes implevit bonis:
et divites dimisit inanes.
Suscepit Israel puerum suum:
recordatus misericordiae suae.
Sicut locutus est ad patres nostros:
Abraham, et semini eius in saecula.
My soul doth magnify the Lord.
And my spirit hath rejoiced in God my Saviour.
Because he hath regarded the humility of his handmaid;
for behold from henceforth all generations shall call me blessed.
Because he that is mighty,
hath done great things to me;
and holy is his name.
And his mercy is from generation unto generations,
to them that fear him.
He hath shewed might in his arm:
he hath scattered the proud in the conceit of their heart.
He hath put down the mighty from their seat,
and hath exalted the humble.
He hath filled the hungry with good things;
and the rich he hath sent empty away.
He hath received Israel his servant,
being mindful of his mercy:
As he spoke to our fathers,
to Abraham and to his seed for ever.
