Menachot 101 - Yom Haatzmaut - April 22, 5 Iyar

The Gemara cites Vayikra 27:11 to teach that blemished animals are called impure. Although the verse refers to "impure animals," there is a different verse (Vayikra 27:27) that explains that impure animals be redeemed; therefore, the first verse must refer specifically to blemished animals.  Shmuel maintains that items consecrated for their value can be redeemed even if they are unblemished. Two difficulties are raised against Shmuel - one by Rav Huna bar Manoach from our Mishna and another by Rav Papa from a braita. Both are resolved by distinguishing between common items and rare items suitable for Temple use; the Sages prohibited the redemption of rare items to avoid a shortage in the Temple. Several rabbis disagree with Shmuel, holding that items dedicated for their value cannot be redeemed if they are pure. There are two versions of Rabbi Oshaya's position regarding whether he agreed with Shmuel. A difficulty is raised against the version that he permitted their redemption, but it is ultimately resolved.
