Joseph & Mary go to Bethlehem

In those days Caesar Augustus issued a decree that a census should be taken of the entire Roman world.(This was the first census that took place while Quirinius was governor of Syria.)And everyone went to his own town to register.And Joseph also went up from Galilee, out of the city of Nazareth, into Judea, unto the city of David, which is called Bethlehem; (because he was of the house and lineage of David:). He went there to register with Mary, who was pledged to be married to him and was expecting a child.And while they were there, the time came for her to give birth. Luke 2:1-6
