DEUT561 When an offering suffers a blemish, redeem it. Hashem in His kindness lets us derive benefit from an animal that was destined for the Altar but suffered a disqualifying blemish and then was redeemed. Although it had been dedicated for the Altar--and it thereby attained special sanctity because the Name of Heaven had been called upon it--Hashem deals graciously with us. He does not command that since His sacred Name was called on the animal for a moment, the animal becomes off-limits forever. Hashem's kindness is so great, He makes it a mitzvah for us to redeem the animal, so that we will have no doubt about the propriety of the matter. Were redemption simply allowed but it was not a positive mitzvot, there would be room to think that those seeking higher levels of piety should not redeem such animals and should not derive benefit from them. For this reason, the Torah states that having redeemed offerings that become blemished, we shall eat of their meat “just as [we eat] of the deer and of the hart,” for the deer and the hart, although they are kosher, cannot be offerings at all. The sanctity of offerings never can descend upon them, and the Torah tells us that a blemished offering after redemption is just like them. The meat is permitted, and one does not need to think twice about eating it.
