I am Jewish and always will be and I do believe that Jesus is God The Messiah ( not that that fact has anything to do with this space ). And I am not considered by my family in Mashiach to be a Messianic Jew. Even though I am and was raised very orthodox in my religion, because of my faith I have adapted myself to God's Law and Word and so my own Jewish religion is quite non-traditional in most groups. Just to set the record straight; please do not lump people all in one boat with broad generalizations - thank you.
In Jewish tradition what is commonly seen spelled in English Rebecca does have a common traditional meaning and it agrees with God's Word and what He says it means too.
