Equal or greater to the possibility that Christians have read INTO Hebrew scriptures predictions that Jesus specifically fulfilled, is that Jewish scholars for centuries have read OUT OF their own scriptures those very same predictions--rationalizing away that Messiah may have been crucified.
Followers of Yeshua have always maintained your 4 major prophesies would indeed be fulfilled in the future by Christ, and that He proved what He claimed by physically rising up from the dead.
The vast number of the passages you cite are not 'predictions' or prophecies at all. They are ordinary statements removed from context. Why are there so many? Because Christians have combed through the Hebrew scriptures looking for any passage at all that they could somehow link to Jesus. Are you familiar with modern literary theory? Christianity is a deconstruction of the text of the Tanakh. You do not read the Hebrew scriptures on its own terms; rather, you read it through Christian spectacles, and then find Jesus everywhere. You are adding meaning to it, not deriving meaning from it. Just as marxist literary theorists read Shakespeare and see class struggle, and feminist literary theorists read Shakespeare and find an oppressive male hierarchy.
From your easy dismissal of the evidence, I suspect you really haven't examined it. Sorry, that's just how it sounds.
You would be wrong. My father is Christian, and my mother is Jewish. I was raised as a Christian, and did not return to the religion of my ancestors until I was an adult. I am quite familiar with the works of Christian apologists from the early church fathers to modern writers such as C.S. Lewis, Peter Kreeft, Josh Macdowell, Lee Strobel, William Lane Craig, et. al. It was my reading of the Hebrew scriptures which convinced me that Jesus could not be the messiah.
