Commentaire sur Le Lévitique 22:22

‎עורת is a noun denoting the blemish of blindness (עִוָּרֹן), being, however, a feminine form of the latter. The text therefore means that there shall not be the defect of blindness in it (in the sacrifice).

עורת או שבור, “blind or having a fractured limb.” Nachmanides writes that seeing the Torah had already listed the blind and broken limbs as disqualifying such an animal it did not have to lengthen the list of disqualifications. It is therefore quite possible that the whole list of disqualifications in our verse applies to the נדבה kind of vow, which was not intended as an offering on the altar in the first place, but was intended as a gift to the Temple treasury. The verse therefore has to be understood as telling us that all the blemishes listed are acceptable in a vow called נדבה, but are not acceptable in a vow called נדר.

[This is] the noun. Explanation: עורת is not the adjective of a female [noun], i.e., a blind animal, because [in] this whole subject [of blemishes, the adjectives are] expressed in the masculine form. Rather, it is a noun like ivaron (blindness), excepting that ivaron is a masculine term and עורת is a feminine term. It is as if the verse said, “The blemish of blindness shall not be in it” (Gur Aryeh). Gur Aryeh means that עורת cannot be the adjective of “animal,” because if so שבורה (broken-limbed) too should have been feminine. Rather it is a noun, like tzedakah and tzedek [righteousness] that both have the same meaning.
