Charles Ellicott Commentary Luke 1:58

"And her neighbors and her kinsfolk heard that the Lord had magnified his mercy towards her; and they rejoiced with her." — Luke 1:58 (ASV)

Her neighbours and her cousins.—Better, her kindred, as including a wider range of relations than that which comes within our definition of cousinship. The words imply that they had heard something of the vision in the Temple, and of what had been foretold of the future greatness of the child then born.

Had shown great mercy upon her.—Literally, had magnified His mercy. The verb is the same as that which opens the Magnificat, and may well be regarded as a kind of echo of it. The phrase is essentially a Hebrew one. (Compare to 1 Samuel 12:24).
