Josephus, Tacitus and Suetonius CONFIRM that JEWS expected the PROPHESIED JEWISH Messianic RULER around c 70 CE using Hebrew Scripture.
Claiming something does no make it true. I have presented how Josephus shows would be Jewish Messianic want a bes goes all the way back to 4 BCE if not earlier.
An Egyptian would NOT even qualify to be a JEWISH Messianic ruler.
Matthew has that whole thing where Jesus' family so that Jesus can came out out of Egypt as supposedly prophesied but Luke doesn't do this and actually has Jesus stay in Judea.
Given Moses had been raised as an Egyptian this may have been the criteria for a would be Messianic ruler. Carrier in fact theorizes the Egyptian may have been a Jew from Alexandria.
In fact in Jewish antiquities Josephus says this:
bout this time,
someone came out of Egypt to Jerusalem, claiming to be a prophet.
He advised the crowd to go along with him to the Mount of Olives, as it was called, which lay over against the city, and at the distance of a kilometer. He added that he would show them from hence how the walls of Jerusalem would fall down at his command, and he promised them that he would procure them an entrance into the city through those collapsed walls. Now when Felix was informed of these things, he ordered his soldiers to take their weapons, and came against them with a great number of horsemen and footmen from Jerusalem, and attacked the Egyptian and the people that were with him. He slew four hundred of them, and took two hundred alive. The Egyptian himself escaped out of the fight, but did not appear any more. And again the robbers stirred up the people to make war with the Romans, and said they ought not to obey them at all; and when any persons would not comply with them, they set fire to their villages, and plundered them. - Jewish Antiquities 20.169-171
Carrier notes that here you have two aspects of the Jesus story: coming out of Egypt and preaching from the Mount of Olives.
Again, maximara you have utterly FAILED to show that HEBREW SCRIPTURE stated that the Prophesied Jewish Messianic ruler would come in the time of Tiberius.
You have not shown that that ALL prophesies of the Jewish Messianic ruler lead to 70 CE nor have you explained all the would be Jewish Messianic rulers that appeared well before that date:
Simon of Peraea (d 4 BCE)
Judas, son of Hezekiah (4 BCE)
Matthias, son of Margalothus (during time of Herod the Great) - thought by some to be the "Theudas" referenced in Acts 5.
Athronges (c 3 CE)
Judas of Galilee (6 CE)
The Samaritan prophet (36 CE) killed by Pontius Pilate.
Theudas the magician (between 44 and 46 CE)
Egyptian Jew Messiah (between 52 and 58 CE). Supposedly led an army of 30,000 people in an attempt to take Jerusalem by force which the Romans drove back killing 400 and capturing 200.
An anonymous prophet (59 CE)
As I said you had various "prophesies" that a would be messiah could point to as a way to "prove" they were the foretold one. If you look at the failed messiahs in Josephus you notice something (unless noted a decade starts at year 1 and ends at 0 so 30s is 31-40 CE):
Herod the Great's death (c 4 BCE) and Census (6 CE): 5
30s: 1
40s: 1
50s: 2
60s: 5 with 1 possibly AFTER the fall of the Temple (Menahem ben Judah)
70s: 1 or 2 (Jonathan, the weaver and Menahem ben Judah)
If as you claim there was a "prophesy" that the would be messiah would come c 70 then we should see the number of claimants slowly increase as that date comes closer. That is NOT what we see but rather an inverted bell curve with Herod the Great's death+Census and the fall of the Temple as the two high points.
