The Roman Emperor during this time was named Augustus and he gave a decree that the whole world would be taxed, and that a census would be taken. He ordered every Jew to return to their ancestral home for the census. Both Joseph and Mary were descendants of David, who was from Bethlehem. They were required by the Roman Empire to immediately go to Bethlehem or be put to death. Joseph knew that Mary was nine months pregnant and ready to give birth, but he obeyed the command of Caesar knowing that God would be with them as they began the long journey from Nazareth to Bethlehem. According to tradition this was during the cold winter month of December.
Augustus Coin
Courtesy of Roman Emperors"And it came to pass in those days, that there went out a decree from Caesar Augustus, that all the world should be taxed. (And this taxing was first made when Cyrenius was governor of Syria.) And all went to be taxed, every one into his own city. And Joseph also went up from Galilee, out of the city of Nazareth, into Judaea, unto the city of David, which is called Bethlehem; (because he was of the house and lineage of David:) To be taxed with Mary his espoused wife, being great with child." Luke 2:1-5
"And she brought forth her firstborn son, and wrapped him in swaddling clothes, and laid him in a manger; because there was no room for them in the inn." - Luke 2:7
