To enrol himself with Mary (apograpsasqai sun Mariam). Direct middle. "With Mary" is naturally taken with the infinitive as here. If so, that means that Mary's family register was in Bethlehem also and that she also belonged to the house of David. It is possible to connect "with Mary" far back with "went up" (anebh) in verse Acts 4 , but it is unnatural to do so. There is no real reason for doubting that Mary herself was a descendant of David and that is the obvious way to understand Luke's genealogy of Jesus in Luke 3:23-38 ). The Syriac Sinaitic expressly says that both Joseph and Mary were of the house and city of David. Betrothed (emnhsteumenhn). Same verb as in Luke 1:27 , but here it really means "married" or "espoused" as Matthew 1:24 shows. Otherwise she could not have travelled with Joseph. Great with child (enkuwi). Only here in N.T. Common Greek word.
