Luke 2:4-7

4and Joseph also went up from Galilee out of the city Nazareth to Judaea, to David's city, the which is called Bethlehem, because he was of the house and family of David,

5to be inscribed in the census roll with Mary who was betrothed to him [as his] wife, she being great with child.

6And it came to pass, while they were there, the days of her giving birth [to her child] were fulfilled,

7and she brought forth her first-born son, and wrapped him up in swaddling-clothes and laid him in the manger, because there was no room for them in the inn.
