Luke 2:1–7 (NIV)
1 In those days Caesar Augustus issued a decree that a census should be taken of the entire Roman world.
2 (This was the first census that took place while Quirinius was governor of Syria.)
3 And everyone went to their own town to register.
4 So Joseph also went up from the town of Nazareth in Galilee to Judea, to Bethlehem the town of David, because he belonged to the house and line of David.
5 He went there to register with Mary, who was pledged to be married to him and was expecting a child. 6 While they were there, the time came for the baby to be born, 7 and she gave birth to her firstborn, a son. She wrapped him in cloths and placed him in a manger, because there was no guest room available for them.
