In the Old Testament, the oldest son of Asenath and Joseph who was sold into Egypt (Gen. 41:50–51). He and his brother Ephraim were grandsons of Jacob (Israel) but were adopted and blessed by him as if they were his own sons (Gen. 48:1–20).
Manasseh’s descendants were numbered among the tribes of Israel (Num. 1:34–35; Josh. 13:29–31). Moses’ blessing of the tribe of Joseph, which was given also to Ephraim and Manasseh, is recorded in Deuteronomy 33:13–17. Their assigned land was partly west of the Jordan and next to Ephraim’s. They also had colonies east of the Jordan in the rich pastureland of Bashan and Gilead. In the last days, the tribe of Manasseh will assist the tribe of Ephraim in gathering scattered Israel (Deut. 33:13–17). The Book of Mormon prophet Lehi was a descendant of Manasseh (Alma 10:3).
