The Midrash Rabba Bamidbar 14:1 (Naso), talks about Moshiach ben David, Moshiach ben Efrayim and Eliyahu.
On the verse "Gilead is mine and Menashe is Mine" (Tehillim 60), the Midrash says that this is referring to the "Moshiach who will spring from the Bnei Menashe".
Who is this "Moshiach ben Menashe"?
