Luke 2:4-7

4And Joseph also went up from Galilee, out of the city of Nazareth, into Judæa, to the city of David, which is called Bethlehem, because he was of the house and family of David; 5to enrol himself with Mary, who was betrothed to him, being great with child. 6And it came to pass, while they were there, the days were fulfilled that she should be delivered. 7And she brought forth her firstborn son; and she wrapped him in swaddling clothes, and laid him in a manger, because there was no room for them in the inn.
