Does anyone have access to the Mossad HaRav Kook edition of Rabbi Yosef Bechor-Shor's peirush (commentary) on the Torah? Specifically, if anyone is able to scan and upload an image of the section(s) where he talks about the Nachash HaNechoshet, that would be great. It is Sefer Bamidbar, Perek 21. It really doesn't have to be the Mossad HaRav Kook version in particular, but I think it is better because of the super-commentary that some of their seforim have. I want to see this because my rabbi-friend pointed out to me that the Artscroll Chumash quotes the Bechor Shor here and we both wanted to "see it inside." If you help me obtain this, then you are also fulfilling the mitzvah of Shimush Chachamim.
