Pilate's biographical details before and after his appointment to Iudaea are unknown, but have been supplied by tradition, which include the detail that his wife's name was Procula (she is canonized as a saint in Orthodox Christianity) and competing legends of his birthplace.
1 Now on the same occasion there were some present who reported to Him about the Galileans whose blood Pilate had mixed with their sacrifices. 2 And Jesus said to them, "Do you suppose that these Galileans were greater sinners than all other Galileans because they suffered this fate? 3 "I tell you, no, but unless you repent, you will all likewise perish. 4 "Or do you suppose that those eighteen on whom the tower in Siloam fell and killed them were worse culprits than all the men who live in Jerusalem? 5 "I tell you, no, but unless you repent, you will all likewise perish." Luke 13:1-5 (NASB)
The famous Pilate Inscription found at Caesarea Palaestina refers to Pilate as prefect, while Tacitus speaks of him as procurator of the province. The explanation of the differences in title is fairly straightforward.
In the first historical period in which the setting of the New Testament became the Roman Iudaea Province (a compound of Samaria, Judea and Idumea), from 6 to the outbreak of the Great Jewish Revolt in 66, officials of the equestrian order (the lower rank of governors) governed. They held the Roman title of prefect until Herod Agrippa I was named King of the Jews by Claudius.
