Luke 2:19 - Ellicott's Commentary On The Whole Bible

Mary kept all these things. — On the assumption that the whole narrative is traceable to the Virgin herself as its first author, these brief and simple touches as to her own feelings are of singular interest. She could not as yet understand all that had been said and done, but she received it in faith, and waited till it should be made clear. It was enough for her to know that her Child was, in some sense, the Son of God and the hope of Israel. The contrast between the simplicity and purity of St. Luke’s narrative, and the fantastic and often prurient details of the Apocryphal Gospel of the Infancy is every way suggestive.
