Mary and Elizabeth
Mary then goes and visits her relative Elizabeth. Upon meeting the pregnant Mary, Elizabeth feels John move in her womb and is "...filled with the Holy Spirit." (41) This might be related to Genesis 25:22. Elizabeth gives praise to Mary, and Mary, in her Magnificat, gives praise to God. She first thanks God for favoring one so "humble" as her, then praises God for his "mercy" and "help" to all people. Many see the Magnificat patterned on Hannah's prayer in 1 Samuel 2:1-10. (Brown 232)
In verses 51-53 Luke uses the past tense six times, implying Jesus' conception has fulfilled or is fulfilling these actions of God. These verses speak of the downfall of the proud and rich and the favor of the downtrodden. This might be a general statement, or an allusion to Israel and its Gentile rulers. Some have speculated these represent Ebionite views. Mary then mentions Abraham, again linking this with God's original covenant. (Brown et al. 681) Mary stays for three months and leaves shortly before John's birth. Some find the idea of a young pregnant woman making the trip from Jerusalem to Nazareth improbable, but it is certainly not impossible.
