What is the difference between Haza'ah and Mitzuy (both of which are mentioned in this Pasuk)?
Rashi: Mitzuy is pressing the Oref against the wall of the Mizbe'ach until the blood drips down. Haza'ah is performed by holding it by the neck and shaking towards the Mizbe'ach, and the blood sprinkles on the Mizbe'ach.
Why does the Torah write "Chatas Hu"?
Rashi: It is Kosher only if it is brought Lishmah, but Pasul if it is brought Lo Lishmah.
