Why does the Torah mention Yosef in relation to Menashe but not Ephraim in the story of the spies?
In the beginning of Parshat Sh'lach, when listing the spies from each tribe, the Torah gives Ephraim like every other tribe (Bamidbar 13:8):
למטה אפרים הושע בן-נון
From the tribe of Ephraim, Hoshea the son of Nun
However, a few verses later (Bamidbar 13:11), when discussing Menashe, it specifically mentions Yosef (Menashe and Ephraim's father):
למטה יוסף למטה מנשה גדי בן-סוסי
From the tribe of Yosef, from the tribe of Menashe, Gadi the son of Susi
Why does the Torah specify that Menashe is part of Yosef, but doesn't do the same for Ephraim?
