Reply To: Dvar Torah Vayigash — Power Should Not Always Corrupt :

I am extending what Rashi says mishom teitzei haroah, from Goshen will come psak and also through Yehuda. Maybe that was the reason that later Yehuda took over psak, which interesting as you would think that the Torah delegates it to the kohanim who did not work. It was the execution of halachas but not the derivation. Yehuda was the nasi who did not need to be supported either, so they had time to work on the Torah.
