Matthew Poole and continuators on Luke 1:41

41 And it came to pass that when Elizabeth heard the salutation of Mary, the babe leaped in her womb: and Elizabeth was filled with the holy Ghost.

The motion of the Child in the Womb of the Mother, after her time of quickening is past, and the more then ordinary motion of it, upon some extraordinary cause of joy, is no unusual thing with Women in those circumstances, but doubtless as this▪ motion was more then ordinary, so it had a more then ordinary cause, being caused from the Holy Spirit of God, and so the best Interpreters Judge, what is afterward said of Elizabeth, that she was filled with the Holy Ghost, is expounded in the next Words, wherein she Prophecieth, of the Spirit of Prophecy.
