Karetot 27: The Status of a Sacrifice Not Yet Brought to the Temple, pt. 2

Today's daf is the second to last of Massechet Karetot.  The rabbis ask what should be done with an animal that has been set aside as a sacrifice when the owner then dies?  The Mishna teaches us that the person's son cannot bring that sacrifice in his father's place.  

Rambam (Commentary to the Mishna) says that this is obvious because in daf 21 we learned that an animal prepared for sacrifice is left to die as a tereifa if its owner dies.  Perhaps this means that the son cannot use the sacrifice of his own should his father die.  Tosafot Rabbeinu Peretz teaches that we need to be taught this law because it is not obvious that the son would not stand in his father's place.

The Mishna focuses on the status of a sin offering.  A similar law applies to an asham, a guilt offering.  If the owner of the sacrifice dies, the animal cannot be sacrificed.  It will be put to pasture until it develops a blemish, making it impossible to sacrifice.  At that point it is redeemed and another sacrifice will be purchased with that money.  Other sacrifices including an ola, burnt offering, and shelamim, peace offering, must be sacrificed by children of the one who died.  The sacrifices will not be done in his name, however.  Massechet Zevachim (5b) discusses in greater detail whether the sacrifice should be viewed as belonging to the child or the person who has died.
