Luke 2:1-7

Now in those days a decree went out from Caesar Augustus to register all the empire for taxes. This was the first registration, taken when Quirinius was governor of Syria. Everyone went to his own town to be registered. So Joseph also went up from the town of Nazareth in Galilee to Judea, to the city of David called Bethlehem, because he was of the house and family line of David. He went to be registered with Mary, who was promised in marriage to him, and who was expecting a child. While they were there, the time came for her to deliver her child. And she gave birth to her firstborn son and wrapped him in strips of cloth and laid him in a manger, because there was no place for them in the inn.
