DEUT566 Do not eat meat of sin offerings or guilt offerings outside of the courtyard of the Beis HaMikdash. One eats meat of the offerings in a specially designated place, so that those to whom the meat is permitted will eat with the proper intention. Regarding sin offerings and guilt offerings, our Sages teach, “The Kohanim eat and thereby, the owners of the offerings attain atonement,” and the Kohanim must keep this idea in mind while eating. Were they allowed to eat the meat wherever they pleased, they would be distracted from the purpose of their eating.
