The gospels were written decades after Jesus is said to have died, with virtually no corroborating evidence that the details contained in the accounts happened. It would not be difficult for the gospel writers to include information that aligns with OT writings to make their story more compelling.
The stories in the NT are extraordinary. What I find more extraordinary though is that a man was creating huge issues with the Pharisees, performing miracles and raising dead people, and history is virtually silent about this, apart from the founders of this new religion.
It is far more logical to think the coincidences with prophecy never happened at all, and were added to manipulate the simple people of the times to join.
