Luke 2:4

4 And Joseph also went up from Galilee, out of the city of Nazareth, into Judaea, unto the city of David, which is called Bethlehem; (because he was of the house and lineage of David:)

Ver. 4. And Joseph also went up ] By a special providence of God, as is above noted, Luke 2:1 , and not only so, but that the holy virgin might still have with her the keeper and cover of her virginity; that the devil might not have occasion to raise up false reports about her great belly.
