Комментарий к Бамидбар 1:10

לבני יוסף לאפרים, “For the children of Joseph,- for Ephrayim;” after the Torah had first enumerated all the sons of Leah it now turns to the sons of Rachel, mentioning Ephrayim ahead of Menashe the older seeing Yaakov had blessed Ephrayim first on is deathbed (compare Genesis 48,20). Afterwards the Torah mentioned the descendants of Binyamin. Although born last, the Torah honoured the memory of Rachel by mentioning him ahead of the sons of the maidservants. When listing the four sons of the maidservants, the Torah begins with Dan who was the senior of those four sons, whereas the Torah lists Asher next seeing that he was encamped next to Dan (compare 2,27). Next the Torah lists Gad who was the older of the sons of Zilpah. Next to him was Naftali.

לבני יוסף, “of the Children of Joseph;” they are mentioned after the children of Leah as a sign of respect to their mother Rachel. The Torah mentions the younger son Ephrayim first, as this is what their father Yaakov did when he blessed them before his death. (Ibn Ezra) Ephrayim and Menashe, though grandsons of Yaakov, are mentioned before his son Binyamin, as combined they represented Rachel’s firstborn son Joseph.
