Ramban asks: if Rashi is correct, then why did none of Bilhah or Zilpah’s children speak up to defend Yosef or try to save Yosef when the other brothers were planning to kill him or sell him? Not only did they not object, but it seems from the story that ALL the brothers, except for Reuvain, consented to the sale!This point would be a davar pashut if not for certain blogs and sites that pretend otherwise. I’ll put it bluntly: if you read the story of Yosef and his brothers as revolving around petty jealousies, dysfunctional family relationships, or sibling rivalry, you are not learning chumash – you are reading a novel or a work of literature. An isolated Ramban or a statement by Hirsch or some other comment here or there that is critical of the Avos does not change the fact that the meta- assumption when learning chumash, as opposed to reading the Bible as literature, is that the Avos, the shevatim, etc. were tzadikim that did not share the same gross character imperfections and faults that the average Joe does.
The question of what to do with Yosef was debated by the shevatim as an issue of devarim ha’omdim b’rumo shel olam, a din Torah that they knew would have repercussions for the future of Klal Yisrael. Personal interests had nothing to do with it! To think otherwise is to completely misunderstand the issue and the personalities involved.
Therefore, whether Yosef was close to the children of the shefachos or not close to them could not help (or hurt) his cause. All that mattered was getting to the objective truth of what needed to be done.(So you’ll ask: what’s the Ramban’s question then? It could be that what bothered Ramban is the fact that things got to that point. Why didn’t any of the brothers friendly to Yosef step in earlier to defuse the situation?)
