Leviticus 10:12-13

12Moses said to Aaron and his remaining sons, Eleazar and Ithamar, “Take the grain offering left over from the food offerings prepared without yeast and presented to the LORD and eat it beside the altar, for it is most holy. 13Eat it in the sanctuary area, because it is your share and your sons’ share of the food offerings presented to the LORD ; for so I have been commanded.
