The concept of "Messiah ben Joseph" refers to a figure in Jewish tradition, specifically rabbinic literature, who is distinct from the more commonly known Messiah ben David. Messiah ben Joseph is prophesied to come from the tribe of Joseph (specifically, Ephraim) and is described as a suffering, warrior figure who will play a crucial role in the events leading up to the Messianic Age. His death and resurrection are believed to precede the final redemption brought by Messiah ben David.
