A.T. Robertson Commentary Luke 1:46

"And Mary said, My soul doth magnify the Lord," — Luke 1:46 (ASV)

Doth magnify (μεγαλυνε). Latin, magnificat. Harnack argues that this is also the song of Elisabeth because a few Latin MSS. have it so, but Mary is correct. She draws her material from the O.T. and sings in the noblest strain.
