 The Testament of Benjamin was probably expanded later to include a reference to Messiah ben Joseph by Jewish sources.The Testament of Joseph on the other hand was probably altered by Christians to read that the virgin born Lamb of God from the tribe of Judah rather than the lamb son of Joseph would conquer.The Talmud uses the Hebrew "ben" rather than the Aramaic "bar" when giving the lineage of these messiahs, suggesting a date before 200 CE.
