Tur HaArokh
אפרים ומנשה כראובן ושמעון יהיה לי,” Ephrayim and Menashe will be to me just as Reuven and Shimon.” It appears from Rashi’s commentary that the division of the land in the days of Joshua was not based on the actual claimants, the sons of Yaakov still being alive at the time, but it was based on a principle known as גלגול, re-incarnation. It did not matter therefore, that Yaakov appeared to have compared the younger son Ephrayim, to Yaakov’s eldest, Reuven. Ephrayim and Menashe were to be “tribes” in name only, they did not replace the concept of “the tribe of Joseph.” [the cut off point for being included in the original family of Yaakov was the date of their arrival in the land of Egypt. Seeing that both Ephrayim and Menashe had been born prior to Yaakov’s arrival, even though they had been born on the contaminated soil of Egypt, enabled Yaakov to confer the status on them that he is about to bestow. Ed.] Nachmanides questions the wordsעל שם אחיהם יקראו בנחלתם, “they will be included under the names of their brothers in their inheritance,” claiming that these very words indicate that the “name” is of the essence, not as Rashi suggests that they were “tribes” in name only. Besides, Nachmanides holds that the land division under Joshua was not based on the original Israelites who had left Egypt being considered as having been resurrected, and the size of the land holdings being based on the size of their families at that time, but that each tribe received the same size of territory in the Land of Israel, although the parcels were not of equal quality as farmland, etc. When the Torah had instructed that the more numerous tribes should receive larger portions of land, whereas the less numerous ones would receive a smaller share, (Numbers 26,4) this referred to the basic family units within the tribe, not to the tribes themselves. These family units were based on the state of affairs of the families when they left Egypt. [if, due to the sin of the spies and the death decreed on that whole generation, taking possession of the land had not been postponed by 40 years, a whole generation, there would not have been a problem in understanding the instructions of the Torah. Ed.] It is therefore quite easy to understand that the tribal portions allocated to Ephrayim and Menashe by Yoshua equaled those of Reuven and Shimon.]
Chizkuni
ושברתי את גאון עוזכם, “I will break the pride of your power;” this has to be contrasted with verse 13 where the Torah described G-d as breaking all the yokes that the Egyptians had used to keep the Israelites down. This is stage one in this process of humbling the Jewish people. Step two follows with: ונתתי שמיכם ברזל, “I will make your heaven as iron;” this is the contrast to verse 4 where rain was promised to fall at the appropriate time of the year.
Chizkuni
ואת ארצכם נחושת, “and your soil like copper.” This contrasts the word בעתם, “at their proper time” in verse 4 above. This was a separate blessing, i.e. the third one.
