Have you ever heard that you cannot be a convert or of Israel without being of a tribe? Do you believe in twelve tribes of Israel but not the converts?Jacob, I really do not understand what kind of Judaism you have converted to. Nothing is right about the things you have created about you. I doubt if you really converted because no Rabbi would have accepted your application with these ideas about being both, Jewish and Christian. And above all, you even want to belong to a Tribe in Israel. Well, I think you had a dream.
If a person discovers that they are of Israel or Jewish, they may want to know what tribe they are of. That was not the case with me. I did not discover myself to be of Israel. That is not how I became a convert.
As for the proselyte in the Bible, that can be a whole or entire study.
There are many Rabbis that I have learned from. I also know that it is possible to be Jewish and believe in Yeshua as the Messiah without being Messianic.
