Luke 2:4-7

4So Joseph also went up from Nazareth in Galilee to Judea, to the city of David called Bethlehem, since he was from the house and line of David. 5He went there to register with Mary, who was pledged to him in marriage and was expecting a child.

6While they were there, the time came for her Child to be born. 7And she gave birth to her firstborn, a Son. She wrapped Him in swaddling cloths and laid Him in a manger, because there was no room for them in the inn.
