Matthew Poole and continuators on Numbers 13:11

11 Of the tribe of Joseph, namely, of the tribe of Manasseh , Gaddi the son of Susi.

(i. e.) Of that part of the tribe of Ioseph, which is peculiarly called the tribe of Manasseh, [illegible: 1 word] the other part of it was called the tribe of Ephraim, ver. 8. The name of Ioseph is elsewhere appropriated to Ephraim, as Ezek. 37. 16, 19. Rev. 7. 8. here to Manesseh, possibly to aggravate the sin of the ruler of this tribe, who did so basely degenerate from his noble ancestor, Ioseph.
