Rashi explains the concept of ‘Kol yisroel beni melchim’ to mean that we are not meant to differentiate between groups. Rashi earlier (67a) explained that all of Yisroel are actually regarded as princes. How do we resolve this apparent discrepancy in Rashi?
Rashi cites the tying of the ‘Yerios’ as the source for the melacha of Kosher, which seems a bit difficult in view of the fact that the Gemara (74b) seemed to have retracted from this as the source of Kosher.
