"Jesus Was A Jew" explored what the traditional Jewish view was of what the Messiah would be like and what he was coming to do, then it examined how well Jesus matched these expectations. The target audience seemed to be Jews, but Christians will find this information very interesting as well, especially if you wish to discuss Jesus with non-Messianic-Jews.
The author examined what the Hebrew scriptures said about the Messiah with a focus on those passages that modern Jews are usually taught have nothing to do with the Messiah. He quoted the Talmud, Midrash, Targums, Septuagint, and more to show what pre-Jesus Jewish teachers taught about the Messiah (especially in reference to these passages).
The author also explained why Jesus had to die, answered Jewish objections to Jesus, and explored the definitions of what it means to be a Jew, Gentile, and Christian.
The book was well-written, interesting, and easy to understand. Overall, I'd highly recommend this book to those who want to know how to respond to Jewish objections to Jesus as the Messiah or who want to know a little more about the pre-Jesus view of the Messiah.
