Your seeing the Jews undergoing the GT and not who Jesus said in Matthew 24:9
https://biblehub.com/interlinear/matthew/24.htm
In fact in ad70 those who endured the siege of Jerusalem are seen by many as such in this but in Matthew 24:9 he said "...they will deliver
you(the disciples/Church) and that they would be hated for the
name of him(Jesus) so bare in mind that 1.1 million Jews died in the siege and 6 million in ww2(which is sorrowful) but of those not one of them died
for Jesus name's sake(they don't believe Jesus is the Messiah we do and we face the GT).
In Mat 24:9, who did Jesus say would die for His name's sake? Who was Jesus talking to? Look at the 3 companion passages. The answer is found in Mk 13: 3
"Now as He sat on the Mount of Olives opposite the temple, Peter, James, John, and Andrew asked Him privately..." Thus, depending on which of the four He was looking at, He was talking to them, not some distant audience. Thus we should expect to find examples of the below happening to some, or all, of the above 4.
Mat 24:9 “Then they will deliver you up to tribulation and kill you, and you will be hated by all nations for My name’s sake.
Mark 13:9 “But watch out for yourselves, for they will deliver you up to councils, and you will be beaten in the synagogues. You will be brought before rulers and kings for My sake, for a testimony to them. 10 And the gospel must first be preached to all the nations. 11 But when they arrest you and deliver you up, do not worry beforehand, or premeditate what you will speak. But whatever is given you in that hour, speak that; for it is not you who speak, but the Holy Spirit. 12 Now brother will betray brother to death, and a father his child; and children will rise up against parents and cause them to be put to death. 13 And you will be hated by all for My name’s sake.
Luke 21:12 But before all these things, they will lay their hands on you and persecute you, delivering you up to the synagogues and prisons. You will be brought before kings and rulers for My name’s sake. 13 But it will turn out for you as an occasion for testimony. 14 Therefore settle it in your hearts not to meditate beforehand on what you will answer; 15 for I will give you a mouth and wisdom which all your adversaries will not be able to contradict or resist. 16 You will be betrayed even by parents and brothers, relatives and friends; and they will put some of you to death. 17 And you will be hated by all for My name’s sake.
Taking all three companion passages together we know that of the group of Peter, James, John and Andrew some of these 4 were put to death. History tells us 3 of them were. All were subject to persecution. We have several examples of some being delivered up to councils, synagogues and prisons. Let's see if we can find fulfillment of the above with these 4.
Peter: Acts 4 is the first example of Peter and John being arrested and brought before the Jews and threatened. We find Peter in prison in Acts 12. We all know the predictions Jesus had for Peter being led away when he was old. Peter was brought before Nero and later killed by Nero.
James: James, the brother of John was killed by King Herod by sword in Acts 12. James, the half-brother of Christ was thrown from the temple roof in 66 AD and later that same day, the Romans arrived. Since Peter and Andrew were brothers, it is reasonable to assume brothers John and James were the other 2. Thus James, the brother of John, was the first of the 4 to be martyred.
John: Was arrested with Peter in Acts 4. Early church tradition says that Nero attempted to kill John by dumping him in a vat of boiling oil, but John was unharmed thus Nero banished him to Patmos.
Andrew: The Bible says little about Andrew but church tradition claims Andrew was martyred by crucifixion in the city of Patras (Patræ) in Achaea. Early texts, such as the Acts of Andrew known to Gregory of Tours describe Andrew as bound, not nailed, to a Latin Cross of the kind on which Jesus is said to have been crucified; yet a tradition developed that Andrew had been crucified on a cross of the form called crux decussata (X-shaped cross, or "saltire"), now commonly known as a "Saint Andrew's Cross" - supposedly at his own request, as he deemed himself unworthy to be crucified on the same type of cross as Jesus had been.
Thus in these four disciples, the one Christ spoke to in the above 3 companion passage fit every things Christ predicted. Thus there is no need to keep looking for future fulfillment to peoples thousands of years later.
