Josephus and other contemporaries on Jesus

[Minimalist]

The Bible commands "Jesus" to be referred to as Immanuel.  So Josephus is false since he does not mention an Immanuel.

Ah, no.

Josephus refers to Jesus as the messiah which is a title of Jesus in the bible. Messiah was what the Jews were looking for to physically deliver them from the Romans. Later a false messiah lead the jews to their destruction is what Josephus is leading up to.

Josephus, who had nothing good to say about the leaders of the Great Revolt, died before the 2d and 3d Jewish revolts.  So unless you are prepared to grant him the gift of prophecy you are full of shit as usual.
