Muhammad in the Bible? Not really

Since Jews claim to be the most knowledgeable of their own main scripture (the Old Testament), I thought that it would be best for me to collect their refutations to the Christians.

Just in case your a Christian and your thinking to your self "well then that means the Jews are justified in rejecting Islam since they know that Muhammad isn't predicted in the Torah." Well actually that isn't the case since we don't hold the Old Testament that is possessed today in the hands of the Jews and Christians as authoritative, but we believe that the Prophet Muhammad (peace be upon him) was predicted in the Torah revealed to Moses (peace be upon him) and some of those parts have survived and are scattered throughout the Bible. But since Christians hold the entire Old Testament as authoritative, they should be concerned about the arguments that the Jews have put forth against them.
