What happens to the Shelamim? Who eats it?
Zevachim (5:6): The owner eats it (and may give others to eat it) anywhere in Yerushalayim, but only for one day. Only Kohanim and their families and their (Kena'ani) slaves may eat their portion. 1
I.e. the foreleg, and [like from every Shelamim] Chazah v'Shok (verses 19,20).
Seeing as it is disrespectful to shave in the Azarah, how can the Torah write that the Nazir shaves "Pesach Ohel Mo'ed"?
Rashi: "Pesach Ohel Mo'ed" is a way of saying that the Nazir should shave after bringing the Shelamim - which are slaughtered at the entrance of the Ohel Mo'ed. 1
Bearing in mind that the Shalmei Nazir may be eaten anywhere in Yerushalayim, why must it be cooked in the Azarah?
