Exodus 29:34-36

Evangelical Heritage Version

³⁴ If any of the meat or the bread from the ordination remains until the next morning, you shall burn the remainder with fire. It must not be eaten, because it is holy.

³⁵ This is what you shall do to Aaron and to his sons, exactly as I have commanded you. You shall ordain them^[a] for seven days. ³⁶ Every day you shall offer a bull as a sin offering for atonement, and you shall purify the altar when you make atonement for it, and you shall anoint it to make it holy.
