You asked rhetorically, "How many scholars in his day expected the Messiah to come as the Suffering Servant?"
Upon what do you base your belief that a lot or most Jewish "scholars" (scribes?) "expected the Messiah to come as the Suffering Servant"?
NO - you misunderstood what I said. They read the suffering servant passage as being about the people of Israel as a whole, rather than being about the Messiah.
They thought, according to what I have read, the Suffering Servant referred to the experiences of exile, then restoration.
The idea I was saying is:
God fulfills prophecies the way God fulfills prophecies. It is possible to have an entire concept that makes sense put together, but that doesn't mean that's the way God reads it.
God is the master, and we are here, doing his will, if we love him. You can be sure He will fulfill the prophecies exactly the way he has in mind, and don't be surprised if that's not exactly the way others thought it ought to have been done.
