Who is allowed to slaughter the animal for a sacrifice? The mishna words it in a way that sounds like it is only post facto allowed – however this contradicts another source which indicates it is permitted ab initio. The mishna also indicated that if an impure person slaughtered. it is allowed, however another source contradicts and seems to indicate it is not allowed. Ula explains that an impure person who even puts a bit of one’s body into the azara of the mikdash it is forbidden. A question is brought from a tannatic source against him and a potential proof is brought. Both are rejected.
