Luke 2:1-5

1Now in those days a decree went out from [the emperor] Caesar Augustus, that all the inhabited world (the Roman Empire) should be registered [in a census].

2This was the first census taken while Quirinius was governor of Syria.

3And everyone went to register for the census, each to his own city.

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

5in order to register with Mary, who was betrothed to him, and was with child.
