Deuteronomy 33:16-17

16with the best gifts of the earth and its fullness and the favor of him who dwelt in the burning bush. Let all these rest on the head of Joseph, on the brow of the prince among his brothers.

17In majesty he is like a firstborn bull; his horns are the horns of a wild ox. With them he will gore the nations, even those at the ends of the earth. Such are the ten thousands of Ephraim; such are the thousands of Manasseh.”
