PW I don't think that you are the one who left the verse about "before the rebellion and commotions" out. In fact I had seen it applied many years ago long before we spoke of it today but if by how I worded my post made you think so I apologize.
As I said about seeing this in the past I also had looked into this from the point of when and how the war first began and the commotions Josephus would be referencing. In Josephus: Of the War, Book II ,,,beginning around chapter 14 Florus https://en.wikipedia.org/wiki/Gessius_Florus who is appointed procurator in ad64-66 are the commotions that led up to the rebellion. So if Josephus states that these things that were seen were (before) those commotions began then ad63 is the year "before" Florus was made procurator and began trying to cause a war. Pella was laid waste by the Jews at that same time(see chapter 18.1) So again if in ad63 Jesus returned or these signs were to be noted the apostles were still there and would have said that he had returned.

It's also interesting that the disciples asked for the signs leading up to the return of Christ. I presume they did this so that they'd know when He was about to return. Nowhere in Christ's answer does He say, "Don't worry about the signs, you guys are going to be long dead and buried because I'm not coming back for a very long time." But, He didn't say anything of the sort. He told them the signs and one of them was that they would be hated, and even killed. Why give 1st century signs for an event that would be thousands of years later? If Christ was discussing a 21st century return why not use signs relevant to our times, like computers, television, space travel, internet, planes, cars, etc.?
Just curious, how do you explain all these strange things Josephus mentioned? Do you see anything divine there? Do you see anything that happened 66-70 AD time frame worthy of devoting much time too and if so where is it? After all, they were all Jewish and their 2,000 year old nation was about to come to a brutal and devastating end.
