Luke 2:1-4
The Census and the Birth of Jesus
2:1 Now in those days a decree went out from Caesar Augustus to register all the empire for taxes.
2:2 This was the first registration, taken when Quirinius was governor of Syria.
2:3 Everyone went to his own town to be registered.
2:4 So Joseph also went up from the town of Nazareth in Galilee to Judea, to the city of David called Bethlehem, because he was of the house and family line of David.
