The Jewish concept of the Messiah is different than the one developed by the CHristians. The origial Jewish concept was that someone , fully human, would kick the foreigners out of Jerusalum, and become a home grown king, from the house of David.
While I personally doubt that was matthews intention, having someone who was familar with the origininal intention of what the Mosishe would be is certianly feasible in that time period.
Remember, according to the Jewish religion, the Messiah has not come yet.
