What do the words "Asham Hu" come to teach us?
Rashi: It teaches us that even after the owner dies, or after he received his atonement through another animal (e.g. the first was lost, and subsequently found), 1 it remains an Asham, and if it was slaughtered Stam before it was Nitak (given to a shepherd) to graze it, it is not Kosher like an Olah.
Riva, Moshav Zekenim: Even though now it is destined to it graze until it gets a Mum, and its money will be used for Olas Kitz Mizbe'ach.
Rashi: "Asham Hu" is written only after Haktaras ha'Emurim. The Korban is Kasher even if they are not burned at all!
