Exodus 29:34-36

New Catholic Bible

³⁴ If any of the meat of consecration or the bread is left over in the morning, you shall burn whatever is left over with fire; it shall not be eaten, for it is holy. ³⁵ Do to Aaron and to his sons what I have commanded you to do. For seven days you shall consecrate them.

³⁶ The Consecrated Altar and the Daily Sacrifice.“For each of seven days you shall offer a young bull as a sin offering for atonement. You shall also make a sin offering for the atonement for the altar, and shall anoint it to consecrate it.
