Midrash su Levitico 4:23

1) (Vayikra 4:23): "… then he shall bring (his offering a kid of goats, a male without blemish"): even after Yom Kippur, (the Yom Kippur goat not exempting him from this offering, for which he remains liable.) "his offering": He fulfills his obligation with his offering and not with that of his (deceased) father.

1) (Vayikra 4:23) ("If his sin becomes known to him wherein he has sinned in it"): "becomes known" — and not that others tell him. If not for this clause I would say (that he does not bring a sin-offering) only if his bondswoman, (who is "not fit to enter the congregation") informs him (that he has sinned). Whence would I derive (the same) even for his wife informing him? I would exclude his wife (even without the clause), for a woman is not kasher to testify. Whence would I derive (the same) even for relatives informing him? I would exclude relatives, who are not kasher to testify. Whence would I derive (the same) even for a single witness? I would exclude a single witness, who can only make one liable for an oath. Whence would I exclude even two witnesses? It is, therefore, written, (because I would not exclude them otherwise): "becomes known to him" — and not that others tell him.

1) Or, perhaps it (Vayikra 4:24 — "and he shall slaughter … in the place where the burnt-offering is slaughtered") is meant to include (sin-offerings) that are similar to this (the sin-offering of a nassi), viz.: Just as this is characterized by being a sin-offering that is male, fixed, (and not sliding-scale [oleh veyored (see Vayikra 5:6-7)], atoning, coming from the flock, and coming for a known sin — so, I will include all of that kind. What will I include? The idolatry goats, which are a sin-offering that is male, fixed, atoning, coming from the flock, and coming for a known sin. Or, bullocks that are burnt, which are a sin-offering that is male, fixed, atoning, and coming for a known sin — though they do not come from the flock (i.e., this single exception would not bar their inclusion). Or, the festival goats, which are a sin-offering that is male, fixed, atoning, and coming from the flock — though not coming for a known sin. Since they are all (essentially) "equally weighted," let them all be included (as requiring slaughtering in the north).
