Elizabeth was filled with the Holy Ghost - The meaning of this seems to be that she was filled with joy; with a disposition to praise God; with a prophetic spirit, or a knowledge of the character of the child that should be born of her. All these were produced by the Holy Spirit.

Elisabeth was filled with the Holy Ghost - This seems to have been the accomplishment of the promise made by the angel, Luke 1:15, He shall be filled with the Holy Ghost, even from his mother's womb. The mother is filled with the Holy Spirit, and the child in her womb becomes sensible of the Divine influence.

And it came to pass that when Elisabeth heard the salutation of Mary,.... Which might be before she saw her, and at some little distance from her:

the babe leaped in her womb: which motion was not natural, but supernatural; being made at hearing the voice of Mary, who had now conceived the Messiah, whose forerunner this babe, John the Baptist, was to be; and who, by this motion, gave the first notice of his conception, which his mother Elisabeth took from hence; as he afterwards pointed him out by his finger, and by his baptism made him manifest to Israel:

and Elisabeth was filled with the Holy Ghost not with the ordinary graces of the Spirit, for these she had been filled with before, but with extraordinary gifts, with a spirit of prophecy; by which she knew that the Messiah was conceived, and that Mary was the mother of her Lord; that many things had been told her; that she had believed them; and there would be a performance of them; and perhaps it was at this time that John the Baptist was filled with the Holy Ghost also; see Luke 1:15.

The babe (τὸ βρέφος)

See on 1 Peter 2:2.

And it came to pass, that, when Elisabeth heard the salutation of Mary, the babe {o} leaped in her womb; and Elisabeth was filled with the Holy Ghost:

(o) This was no ordinary or usual type of moving.

1:41 When Elisabeth heard the salutation of Mary - The discourse with which she saluted her, giving an account of what the angel had said, the joy of her soul so affected her body, that the very child in her womb was moved in an uncommon manner, as if it leaped for joy.

41. babe leaped-From Lu 1:44 it is plain that this maternal sensation was something extraordinary-a sympathetic emotion of the unconscious babe, at the presence of the mother of his Lord.

1:39-56 It is very good for those who have the work of grace begun in their souls, to communicate one to another. On Mary's arrival, Elisabeth was conscious of the approach of her who was to be the mother of the great Redeemer. At the same time she was filled with the Holy Ghost, and under his influence declared that Mary and her expected child were most blessed and happy, as peculiarly honoured of and dear to the Most High God. Mary, animated by Elisabeth's address, and being also under the influence of the Holy Ghost, broke out into joy, admiration, and gratitude. She knew herself to be a sinner who needed a Saviour, and that she could no otherwise rejoice in God than as interested in his salvation through the promised Messiah. Those who see their need of Christ, and are desirous of righteousness and life in him, he fills with good things, with the best things; and they are abundantly satisfied with the blessings he gives. He will satisfy the desires of the poor in spirit who long for spiritual blessings, while the self-sufficient shall be sent empty away.
