In context
3Everyone went to be registered, each to his own town. 4So Joseph too went up from Galilee, from the town of Nazareth, into Judea, to the town of David called Bethlehem, since he belonged to the house and family line of David, 5to register together with Mary, who was pledged to him and was expecting a child. 6While they were there, the time came for her to give birth, 7and she gave birth to her son, the firstborn. She wrapped him in strips of cloth and laid him in a feeding trough, because there was no room for them in the lodging place.
