1. They include: A non-Kohen, an Onen, a drunk, a Kohen with a blemish, one who is sitting, or one who performs these services with his left hand.
2. If a Kohen needs to put the blood somewhere to be held, he may give it to a non-Kohen to hold before a Kohen takes it from him in order to bring it to the Mizbe'ach. However, if the non-Kohen brings the blood closer to the Mizbe'ach, he disqualifies it.
3. This is evident from his statement, "Nobody ever survived after consulting me about an injury that he received from a white mule." This indicates that people used to ask him for medical advice.
4. The other Avodos that were also considered very difficult were Kemitzah and Melikah.
5. These are: A calf, an undomesticated animal, a slaughtered animal, a Tereifah, Kil'ayim, and a Koy. A sheep should be used.
