Joshua 17:14

And the children of Joseph, the tribes of Ephraim and Manasseh, spake unto Joshua, saying, Why hast thou given me but one lot and one portion to inherit, for the two tribes had been treated as one in the division of the land west of Jordan, seeing I am a great people, forasmuch as the Lord hath blessed me hitherto? So great had been Jehovah's blessing, that is their contention, up to this time, that they had become a numerous people and needed more room. But their objection was not well taken, for not only were the two tribes together less numerous than either Judah or Dan, but the territory assigned to them was also immensely fertile, the plateaus and valleys of this section of Canaan being unsurpassed in this respect.
