Or maybe this ?
“Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the LORD: and he shall turn the heart of the fathers to the children, and the heart of the children to their fathers, lest I come and smite the earth with a curse.”
Malachi 4:5-6 KJV
If we look at what Jesus is saying he interprets thngs
“For all the prophets and the law prophesied until John. And if ye will receive it, this is Elijah , which was for to come. He that hath ears to hear, let him hear.”
Matthew 11:13-15 KJV
many can’t accept that but other do
“But I say unto you, That Elijah is come already, and they knew him not, but have done unto him whatsoever they listed. ( they beheaded John ) Likewise shall also the Son of man suffer of them. ( they crucified jesus )
Then the disciples understood that he spake unto them of John the Baptist.”
Matthew 17:12-13 KJV
Your whole post makes sense to my understanding, but I have re-posted this part because it addresses a matter that I have only recently started paying attention to.
How many prophetic experts could ever have guessed that John the Baptist was the fulfillment of the last prophesy of the OT, had Jesus not told them?
This should serve to humble us when we think we "know" prophesy.
When Abraham and Sarah concluded that they needed to have a son from Hagar they behaved like many who interpret prophesy in this day.
