Exodus 29:34-36

The Voice

³⁴ If any meat or bread is left over from the ordination ceremony the next morning, burn it completely. No one is allowed to eat it, for it is holy.

³⁵ The ordination period is to last for seven days. Here is what you must do to ordain Aaron and his sons to My priestly service. ³⁶ Offer a bull as an offering every day for seven days to purify them from sin. Cleanse the altar and consecrate it by anointing it with oil.
