Daily Aliya for Emor, Shlishi (3rd Aliya)
From Chabad.org: Blemished animals are disqualified for sacrificial use. This Aliya also forbids the castration of animals, sacrificing animals before they are eight days old, and slaughtering a mother animal and her child on the same day. The Aliya concludes with the mitzvah of kiddush Hashem, sanctifying G‑d‘s Name by giving one’s life rather than transgressing certain cardinal sins.
Two probably connected items stand out in this Aliya. First, blemished animals should not be brought because “it will not be favorable for you” (I would think they should be avoided because they aren’t favorable to G-d). Second, the portions of the offering that aren’t burnt at the alter are to be eaten on that day, and not left over for the next day. I think this reinforces the concept that these offerings aren’t for G-d’s benefit, but for us to admit a wrong and move forward. These items take it a step further to insure that the leftovers are favorable to us, and that we enjoy them right away.
