Levítico 4:29 Midrash: Sifra

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).

3) (Vayikra 4:29): "And he shall place his hand on the head of the sin-offering: to include the idolatry sin-offering (of the individual) as requiring semichah. "and he shall slaughter the sin-offering in the place of the burnt-offering:" It must be slaughtered in the north. "in the place of the burnt-offering. And he shall take": (The juxtaposition) indicates that the blood must be received in the north — whence it was derived: If he slaughtered it in the north and received it in the south; in the south, and he received it in the north, it is pasul. It must be slaughtered in the north and (the blood must be) received in the north.

4) "and all of its [remaining] blood he shall pour (at the base of the altar."). And above (Vayikra 4:25) it is written: "and its [remaining] blood he shall pour" — whence it is derived: a sin-offering whose blood was received in four vessels, from each of which he applied (blood at a different corner of the altar) — how do we know that they are all poured out at the foundation, (and not just the first, which effects atonement)? From: "and all of its blood he shall pour."
