Midrash sur Samuel 1 31:13

The men of Jabesh-Gilead showed (loving-kindness) to Saul and his sons. (God said,) I will also give you and your sons your reward in the future; for when the Holy One, blessed be He, in the future will gather Israel from the four corners of the world, the first whom He will gather, will be the half-tribe of Manasseh, as it is said, "Gilead is mine, and Manasseh is mine" (Ps. 60:7). Afterwards (will He gather in) Ephraim, as it is said, "Ephraim is the defence of mine head" (ibid.). Afterwards Judah (will be gathered in), as it is said, "Judah is my sceptre" (ibid.).
