Exodus 29:34-36

Revised Standard Version Catholic Edition

³⁴ And if any of the flesh for the ordination, or of the bread, remain until the morning, then you shall burn the remainder with fire; it shall not be eaten, because it is holy.

³⁵ “Thus you shall do to Aaron and to his sons, according to all that I have commanded you; through seven days shall you ordain them, ³⁶ and every day you shall offer a bull as a sin offering for atonement. Also you shall offer a sin offering for the altar, when you make atonement for it, and shall anoint it, to consecrate it.
