Which chest is Moshe referring to?
Rashi: It refers to the chest of the Shalmei Tzibur.
Can we extrapolate from here that all the previous Korbanos could be eaten in a Tamei location?
Rashi: No. Only the previous Korbanos were all Kodshei Kodshim which could only be eaten in the Azarah; 1 as opposed to the Chazeh ve'Shok of the Shelamim, which are Kodshim Kalim and which may therefore be eaten anywhere within Machaneh Yisrael, and which only require a warning to eat them in a Tahor location within the camp. 2
Having just precluded daughters from receiving a portion in Kodshim, how can the Pasuk now include them?
Rashi: Because this Pasuk is referring (not to receiving a portion but) to eating the Chazeh ve'Shok. 1
Which female Kohanim are permitted to do, since the Shelamim is Kodshim Kalim.
Why does the Torah add the (otherwise superfluous) word "u'Venosecha Itach"?
Zevachim, 87a: To restrict the concession to daughters who as not yet married ? 'be'Zeman she'Itach'.
