Likely you are not aware of the recent drone assisted archeology around Masada. With drones, for the first time, a complete view of the Roman fortifications that Josephus claims took three years to finish were possible to assess. Given the multiple available accounts of how rapidly Roman legions could assemble similar fortifications, that three years looks a lot more like three months.None named or cited. Plenty of the seculars reject historical claims like flood of Noah and Josephus wrote these as historical so it would not be surprising if He was accused by the fashionable moderns as a liar ofr not credible. To the Jews, Josephus was a collaborator with the Romans, so they did not like him at all.
Looks like you are right about that. GROK
Summary: Josephus explicitly claimed personal divine revelation (via dreams and God's prophetic selection) that positioned him as God’s messenger announcing Vespasian’s destiny. He also reinterpreted Jewish messianic-style prophecies as pointing to Vespasian rather than a Jewish deliverer. This self-presentation helped save his life and secure his role as a historian under the Flavians. Note that this is Josephus’ own account; ancient sources like Suetonius confirm the prophecy story but without the same divine framing.
--------------------------
Your earlier claim about late dating for Acts to after 70 is nothing more than speculation without supporting evidence which i do not find compelling.
Josephus claims that Aretas, a Roman client king, attacked Antipas, also a Roman client ruler. A Roman Client ruler attacking another was grounds for removal from office, possibly loss of the kingdom. Aretas died 4 or 5 years after the supposed incident 9in 40 or 41 CE) in office, and his kingdom passed to one of his sons, and then to a grandson. Antipas was inexplicably taken by Vitellius to the Euphrates frontier when Vitellius had to deal with a military problem then returned to Jerusalem alone after Tiberius died in 37 and Gaius Caligula issued many political pardons. Two years later, when Gaius Caligula revoked those pardons, Antipas was removed from office and exiled, as happened to others charged with political offenses.
And a "clearly irrelevant" history just happens to show signs of recording a letter from Tiberius to a different client king, including comments that only fit between 34-6 CE and include Tiberius recognizing Antipas as being implicated in political issues along with Caiaphas, the high priest who was removed in 36, and Pontius Pilate, who was also removed in 36.
And in Acts 2, all the different groups hearing the disciples speaking in tongues, with the exception of Rome, were the first supporters of Vespasian. How is it that no region other than Rome, which took its time deciding who to back in the year of 4 emperors, was present?
Seems like a lot of coincidences to me.
