10 You must learn the difference between what is holy and what isn't holy and between the clean and the unclean.
11 You must also teach the people of Israel everything that I commanded Moses to say to them.
12 Moses told Aaron and his two sons, Eleazar and Ithamar:The grain sacrifice that was offered to give thanks to the Lord is very holy. So make bread without yeast from the part that wasn't sent up in smoke and eat it beside the altar.
13 The Lord has said that this belongs to you and your sons, and that it must be eaten in a holy place.
14-15 But the choice ribs and the hind leg that were lifted up may be eaten by your entire family, as long as you do so in an acceptable place. These parts are yours from the sacrifices that the people offer to ask the Lord's blessing. This is what the Lord has commanded, and it will never change.
16 When Moses asked around and learnt that the ram for the sin sacrifice had already been burnt on the altar, he became angry with Eleazar and Ithamar and said,
17 “Why didn't you eat the meat from this sacrifice in an acceptable place? It is very holy, and the Lord has given you this sacrifice to remove Israel's sin and guilt.
