2nd Perek Summary: “Yesh Bekorbanot”: Differences between individual and communal sacrifices: Communal ones cannot be “exchanged”, there is no “responsibility” for them (i.e. to replace it, if the designated one was lost or stolen), they override the Sabbath and Festivals. However, the opinion of R’ Meir was accepted that the real differentiation for these differences is if the sacrifice has a fixed time or not.
The Law of the Sin-sacrifice that is killed, applies to specific blemishes of an individual’s sacrifice.
Consecration does not apply to a blemished animal, nor on a hybrid, a fatally-ill animal, “tumtum,” androgynous and caesarian.
