I cant see how you would say this if you had read any of the writings of Josephus or any of the other historical writings from that time period.
Why is "Jewish wars","Jewish revolt",,,ect. why is that it is well known that if someone is trying to repel the leadership of a government instead of honouring it then they are "against it" right?
The Jews in the siege were not worshipping Caesar(Nero,Vespasian,Titus ect.) they were "against them" and "revolting" against their authority all the way down to their death in ad70. Then after this the ones who did survive were carried away into captivity(against their will) and those who weren’t killed or carried away regrouped and revolted again and then did the same for the third time years later.
The same Jews refused to use Rome’s money because it had pagan images on them and minted their own
https://en.wikipedia.org/wiki/First_Jewish_Revolt_coinage and so it is impossible to say that they took the mark(money of Rome) if they refused to use it so Revelation 13:17 absolutely could not be fulfilled by those Jews if they did not use Rome’s money.
It used to be a dare in the old days they would say "I dare any of you to read Josephus,ect." as if it would be conclusive in their behalf and in the end what it actually did was prove beyond any doubt that the Jews in ad66-70 absolutely did not worship Caesar nor receive his mark. Past that the only reason why anyone would try to say they did would be for the sole purpose of defending a camp instead of letting things be what they really mean.
