משנה אויף ויקרא 6:18

Most holy sacrifices which were slaughtered on the top of the altar: Rabbi Yose says: it is as though they were slaughtered in the north. Rabbi Yose son of Rabb Judah says: from the middle of the altar southward is as south, from the middle of the altar northward is as the north. The fistfuls of meal-offerings were taken in any part of the Temple court, and they [the minhah-offerings] were eaten within the curtains, by male priests, prepared in any manner, on the same day and night, until midnight.

If the blood of a hatat spurted on to a garment, it must be washed. Though scripture speaks only of [hatats] which are eaten, for it is said, “In the holy place shall it be eaten,” (Leviticus 6:19), yet both those which may be eaten and the inner [sacrifices] necessitate washing, for it is said, “[This is] the law of the hatat” (Leviticus 6:18), there is one law for all hatats.
