1) going along that line, it's interesting that the authors even knew the lineage of Mary or Joseph and they also make it a point to include that jesus has a royal bloodline (presumably to
hammer home that Jesus fulfills the prophecies) and the second part is that the messiah is said to be born in Bethlehem (which is widely accepted that jesus was) and Bethlehem is Josephs (not mary's) fathers
land, but they do end up living in Nazareth, so it makes you wonder a couple of things, why take a very pregnant mary to Bethlehem to have her son?
