So Josephus informs us about what Agrippa had to know
necessarily:
Acts 26:2-3
2 I think myself happy, king Agrippa, because I shall answer for myself this day before thee touching all the things whereof I am accused of the Jews:
3 Especially because I know thee to be expert in all customs and questions which are among the Jews: wherefore I beseech thee to hear me patiently.
Well:
just Agrippa, to which Festus reveals his ignorance about
“a dead man named Jesus” and his way of execution,
just him, is totally unable to inform Festus about the identity of this Jesus.
If this is not a
Strong Argument from Silence against the historicity of Jesus,
pace the subtle objections of DCH above, then
Acts 26:26 is the Greatest Lie of all the times:
“Also King Agrippa especially knows of such things as these, therefore I speak openly before him, because I do not think one of these matters has escaped him, for they were not done in secret.”
Translated: the same author of Acts
denies that there out an
insignificant historical Jesus existed.
