“This was the first registration.

It was taken

When Quirinius was

Governor of Syria.”

αὕτη ἀπογραφὴ πρώτη ἐγένετο ἡγεμονεύοντος τῆς Συρίας Κυρηνίου.

Luke noted that this first registration was taken (αὕτη ἀπογραφὴ πρώτη ἐγένετο) when Quirinius was governing Syria (ἡγεμονεύοντος τῆς Συρίας Κυρηνίου).  Quirinius was the legate of Syria from 6 CE-12 CE.  He was born 51 BCE and died at the age of 72 in 21 CE.  He did take a census or registration for tax purposes in 6 CE when he took over.  This led to the revolt of Judas the Galilean and the formation of the Jewish Zealots, who opposed Roman rule.  They opposed this census for the purposes of taxation by Quirinius, the Governor of Syria.  The one problem is that this census took place 10 years after Herod had died.  However, the birth of Jesus and John was placed during the reign of Herod.  Thus, there is a problem with this dating by Luke, who may have been confused about these historical details.
