Albert Barnes Commentary Luke 1:46

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

My soul doth magnify the Lord. To magnify means to make great, and then to extol, to praise, to celebrate. It does not mean here strictly to make great, but to increase in our estimation—that is, to praise or extol. See Psalm 34:3; 2 Samuel 7:26.
