"In all of your habitations shall you eat matzoth": What is the intent of this? From (Devarim 14:23) "And you shall eat before the L–rd your G–d the tithe of your grain and wine and oil," I might think that if one brought up his second tithe to Jerusalem (and ate it there), he has fulfilled his obligation (of eating matzoh). It is, therefore, written "in all of your habitations"—to exclude this (tithe), which is not eaten in all places (but only in Jerusalem). And whence is it derived that he does not fulfill his obligation, neither with the show-bread, nor with the left-overs of meal-offerings, nor with the thanksgiving challoth, nor with the wafers of the Nazirite, nor with first-fruits? From "in all of your habitations shall you eat matzoth"—to exclude those, which are not eaten in all of your habitations.
