Exodus 29:33-37 They shall eat these things by which atonement was made at their ordination to consecrate them, but an unqualified person is not to eat because these things are holy.

ISV⁽ⁱ⁾ ³³ They shall eat these things by which atonement was made at their ordination to consecrate them, but an unqualified person is not to eat because these things are holy. ³⁴ If any of the flesh of the ordination ram or any of the bread is left until morning, you are to burn what is left with fire. Because it’s holy, what remains is not to be eaten. ³⁵ You are to do this for Aaron and his sons, just as I’ve commanded you. You are to ordain them for seven days, ³⁶ and every day you are to offer a bull as a sin offering for atonement. Offer the sin offering on the altar when you make atonement for it and anoint the altar to consecrate it. ³⁷ You are to make atonement for the altar for seven days and consecrate it. It will be most holy, and whatever touches it will be holy.”
