It's the New Testament of the Bible annotated by Jewish scholars, among them Amy-Jill Levine, who is well known in biblical studies circles for being both a practicing Jew and one of the most pre-eminent New Testament scholars in the world.
As you can imagine, she had a relatively rough time getting to where she is now. One place forced her to teach OT, even though her specialty has always been NT.
Anyway, it's full of brilliant annotations that really help Christians understand the text better while making the New Testament accessible to non-Christians (especially Jewish people, but everyone) in a non-proselytizing way. And it has fantastic essays on the historical developments of Jewish thought regarding various aspects of Christianity.
It should be required reading for every Christian.
