Exodus 29:33-35

Living Bible

³³ They alone shall eat those items used in their atonement (that is, in their consecration ceremony). The ordinary people shall not eat them, for these things are set apart and holy. ³⁴ If any of the meat or bread remains until the morning, burn it; it shall not be eaten, for it is holy.

³⁵ “This, then, is the way you shall ordain Aaron and his sons to their offices. This ordination shall go on for seven days.
