Every male among the priests (who is on duty and is not defiled when the blood is being applied to the Altar, as stated) may eat of the priests’ portions of the sin-offering—but only adult males, for it is a sacrifice of superior holiness, and such sacrifices may be eaten only by the priests themselves, not by their families. The priests may eat their portions only during the day on which the animal is offered up and/or the following night; whatever is leftover on the next day must be burned up.
But any sin-offering—or in fact, any offering whose blood is supposed to be applied to the Outer Altar—some of whose blood was mistakenly brought into the Tent of Meeting in order to effect atonement in the Sanctuary is thereby rendered invalid and therefore must not be eaten. Rather, it must be burned in fire.
