Luke 2:3-6

All returned to their own ancestral towns to register for this census. And because Joseph was a descendant of King David, he had to go to Bethlehem in Judea, David’s ancient home. He traveled there from the village of Nazareth in Galilee. He took with him Mary, to whom he was engaged, who was now expecting a child. And while they were there, the time came for her baby to be born.
