The days of the census are generally understood to be a reference to the census held by P. Sulpicius Quirinius, the governor of Syria-Cilicia. This census took place in 6 AD.1 (To be distinguished from the census of Luke 2:1 which took place around 5 or 6 BC). Together with a Pharisee named Zaddok, Judas the Galilean organized a protest against Roman rule.2 The Jewish historian Josephus also makes mention of him in 18.23 of his Antiquities.
37 Après lui, parut Judas le Galiléen, à l'époque du recensement, et il attira du monde à son parti: il périt aussi, et tous ceux qui l'avaient suivi furent dispersés.
