וגם הוא יגדל, he will also develop into becoming very numerous. However his younger brother will become even more numerous. At the Exodus from Egyptian the arms-bearing males of the tribe of Ephrayim were 45.500 (Numbers 1,33-35 as opposed to only 32.200 members of the tribe of Menashe. Interestingly, when numbering the males over 20 who entered the Holy Land, the members of the tribe of Menashe outnumbered those of Ephrayim by 52.700 to 32.500. (Numbers 26,34-36.) If we keep this in mind we may have to redefine the meaning of the word יגדל when used by Yaakov not as referring to numerical strength, but as referring to the great men produced by each of these tribes and the relative importance of these men. We know that Moses’ successor, Joshua, was from the tribe of Ephrayim. He was a great saviour, and conquered the land of Canaan enabling the promise of G’d to the patriarchs to finally become realised. The tribe of Ephrayim also provided the first king of the 10 tribes who had split away from Solomon’s son Rechavam after the death of Solomon. Furthermore, throughout the history of the Jewish people until the destruction of the first Temple the political rivalry between Ephrayim and Yehudah is well documented, whereas hardly ever is Menashe mentioned as playing a major part in this. When the prophet Isaiah prophesied an idyllic future, he described this as being characterised by the end of the rivalry between Ephrayim and Yehudah. (Isaiah 11,13). Still, it is possible to also understand the word יגדל ממנו as referring to numerical strength, as except in the single instance we mentioned before Ephrayim always outnumbered Menashe. We must also take into consideration the words וזרעו יהיה מלא הגויים, “and his seed will become plentiful enough to form nations.” The unique phenomenon of the members of Ephrayim being inferior in numbers at the time the Israelites entered the Holy Land may possibly be accounted for by the tradition that 30 years prior to the Exodus the tribe of Ephrayim rebelled, left Egypt and marched to the land of the Philistines on the way to the land of Canaan. According to that report they lost 200.000 of their number in a battle at Gat. [the reason why I do not think this relevant is that if so, there should have been fewer member of the tribe of Ephrayim at the time of the Exodus, instead of 40 years later when near entering the Holy Land. Ed.]

בני מנשה למכיר, “as for the sons of Menashe, the ones of Machir, etc.” The names of all the tribes are listed here in the same sequence as they have been listed in Numbers chapter one, with the exception of Ephrayim andMenashe; in this instance Menashe has been named first. The principal reason maybe that it numbered so many more men of military age than the descendants of Ephrayim. While the Jewish people had been in the desert, the number of members of the tribe of Ephrayim had been greater than that of the descendants of Menashe. Furthermore, the flag of Ephrayim’s army group had been the leader of its group, and in that chapter the subject of the flags had first been mentioned, and a tribe leading such a contingent takes precedence over one that merely is an adjunct. In our chapter where the subject is the impending distribution of parts of the Holy Land to the various tribes of the Jewish people, mentioning Menashe, Joseph’s firstborn son first seems appropriate. After all, half of that tribe had also took a substantial portion of their inheritance on the east bank of the Jordan, alongside the tribes of Reuven and Gad.

OF THE CHILDREN OF JOSEPH, NAMELY, OF THE CHILDREN OF EPHRAIM. Scripture mentioned Ephraim before Menasheh, and stated Joseph’s relationship to him [which it does not do in the case of Menasheh],64Verse 34. and similarly later [Scripture gave Ephraim precedence] at the [division of the tribes according to their] standards, by making him master of the standard, [whilst Menasheh is mentioned merely as one of the two tribes gathered around him], because in accordance with Jacob’s blessing65Genesis 48:20. he was to be [given the honor accorded to] the firstborn, and his brother [Menasheh] was to be second to him. Moreover, the sons of Ephraim were more numerous than those of Menasheh66Ephraim totalled 40,500 (Verse 33), whilst Menasheh numbered 32,200 (Verse 35). [and hence Ephraim was mentioned first]. But at the second census in the plains of Moab67Further, 26:3. Scripture mentioned Menasheh first, because at that time his sons were more numerous [than those of Ephraim],68The children of Menasheh were then 52,700 (ibid., Verse 34), whilst Ephraim had only 32,500 (ibid., Verse 37). and [also because] they took their inheritance first.69Half of the tribe of Menasheh joined the tribes of Gad and Reuben in settling during the lifetime of Moses on the east side of the Jordan (ibid., 32:33). Similarly when mentioning the princes of the Land [who were to take possession of the Land for their respective tribes] Scripture mentioned Menasheh first, and also Joseph’s relationship to him.70Ibid., 34:23: Of the children of Joseph; of the tribe of the children of Menasheh. In the following verse Scripture mentions the prince of the children of Ephraim. In [the story of] the spies, however, Scripture mentioned Ephraim first, and Joseph’s relationship it stated only in referring to the tribe of Menasheh.71Ibid., 13:8, 11. It appears to me by way of homiletic exposition that it is on account of the evil report that Joseph brought [to his father] concerning his brothers72Genesis 37: 2. that Scripture, [in the story of the spies], associates with him the spy who [was among those who] spread the evil report [about the Land, namely the spy from the tribe of Menasheh, whereas the spy from the tribe of Ephraim was Joshua the son of Nun, who was not among those who spread the evil report]. Or it may be that Scripture [in relating the story of the spies] gave honor to both [tribes who were descended from Joseph], and Ephraim had sufficient honor in its prince [Joshua the son of Nun who ministered to Moses, therefore Scripture mentioned the honor of descent from Joseph only in the case of Menasheh].
