The idea of dual messiahs is the belief that there are either two messiahs or one messiah assuming the role of two.[1][2] Later-Judaism talks about two messiahs — sons respectively of Joseph and of David.[3][4]
^Jewish tradition speaks of two redeemers, each one called Mashiach. Both are involved in ushering in the Messianic era. They are Mashiach ben David and Mashiach ben Yossef. See Sukah 52b; Zohar I:25b; ibid. II:120a, III:153b, 246b and 252a.
