In those days Caesar Augustus issued a decree that a census should be taken of the entire Roman world. 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. Luke 2:1, 4-5
