I have a Jewish New Testament which I love (Im not Jewish) because its alot of the old original Hebrew and Aramaic words which are original to the texts. I also have a monster concordance and a Commentary for the JNT.
As far as I know, there is no Jewish New Testament. The Jewish Holy book is the Torah. If you mean that your New Testament is written in the way of the Torah, then I'd say that would be a more appropriate explanation.
