The people who wrote the Bible were Jews and well aware of the Jewish prophecies. If they were telling the story of the Messiah, then it would have to fulfill the prophecies. Thus, they would have an interest in making sure it did, wouldn’t they?
Your missing the point. And no, Jews did not want the suffering servant messiah, they were looking for the conquering king messiah. Please, first clearly understand the message. Then study to see if it makes sense that the message is a confabrication of man or if it contains a message that transcends space and time. Or not, your choice.
