Metzora, Chapter 3
1) "For as the sin-offering is the guilt-offering, for the Cohein": Just as the sin-offering comes from chullin (what is mundane [and not from second-tithe]), in the daytime, and (whose blood is sprinkled) with the right hand, so, the guilt-offering. Just as the sin-offering requires a vessel (for the collection of the blood), so, the guilt-offering. Just as (with) the sin-offering, the blood (sprinkled on) the altar permits it (to be eaten by the Cohein), so, (with) the guilt-offering, the altar blood permits it (to be eaten by the Cohanim). If so, let us say: Just as the blood of a sin-offering is applied above (the red line on the altar), so, the blood of this guilt-offering; it is, therefore, written (of guilt-offerings, Vayikra 7:2): "It is holy of holies … and its blood shall he dash on the altar roundabout," to include all of the guilt-offerings, along with the guilt-offering of the leper, as requiring their blood to be applied below (the red line).
