Luke 1:42

“And she spake out with a loud voice,.... So as that all in the house might hear; she spake with great vehemency of soul, and strength of affection, being under a very powerful impression of the Spirit of God: and said, blessed art thou among women; the same words that the angel had said to her before, Luk 1:28. and blessed is the fruit of thy womb: this is a reason why she is called blessed, because her child was blessed; being in union with a divine person, who is God over all, blessed for ever; and who has all spiritual blessings in him, and is that seed, in which all nations of the earth were to be blessed; and so is both blessed in himself, and the source of all blessedness to others. The Jews say (h), that the six measures of barley, Boaz gave to Ruth, Rut 3:15 signified, that six righteous men should spring from her, and among, them the Messiah; who should be blessed with six blessings, and they are these; the spirit of wisdom and understanding, of counsel and of might, the spirit of knowledge, and of the fear of the Lord; see Isa 11:2. (h) Targum & R. Sol. Jarchi in loc.”

“In the same words she is pronounced blessed by Elizabeth, and by the angel Gabriel, both inspired by the Holy Ghost, and this not only to the praise of Jesus, but for his sake, to the praise of Mary, calling her blessed, and her fruit blessed; and thus, as Ven. Bede asserts, holding her up to the veneration of both men and angels.”

“What beautiful superiority to envy have we here! High as was the distinction conferred upon herself, Elisabeth loses sight of it altogether, in presence of one more honored still; upon whom, with her unborn Babe, in an ecstasy of inspiration, she pronounces a benediction, feeling it to be a wonder unaccountable that "the mother of her Lord should come to her." "Turn this as we will, we shall never be able to see the propriety of calling an unborn child "Lord," but by supposing Elisabeth, like the prophets of old, enlightened to perceive the Messiah's Divine nature" [OLSHAUSEN].”
