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.
“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.
This sacrifice is very holy. It belongs to the priest and must be killed in the same place where animals are killed as sacrifices for sins and as sacrifices to please me.
Anything that you completely dedicate to me must be completely destroyed. It cannot be bought back or sold. Every person, animal, and piece of property that you dedicate completely is only for me.
The next morning you will dress in your priestly clothes, including your linen underwear. Then clean away the ashes left by the sacrifices and pile them beside the altar.
From now on, the sacred offerings that the Israelites give to me will belong to you, your sons, and your daughters. This is my promise to you and your descendants, and it will never change.
Don't you know that people who work in the temple make their living from what is brought to the temple? Don't you know that a person who serves at the altar is given part of what is offered?
