Exodus 29:34-36

International Standard Version

³⁴ If any of the flesh of the ordination ram^[a] 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.
