Parashas Metzora · Passuk 14:21
Chabad.org — English translation + Rashi
Torah Temima points to Toras Kohanim.
English: “And his means do not suffice” — one might think [it applies] even if he has [the means] but cannot find [the animals] to purchase; therefore the verse says “and if he is poor.”
Actual poverty required
Chazal require genuine poverty; temporary inability to locate the animals does not entitle one to the reduced offering.
