Exodus 29:34-36

Living Bible

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. ³⁶ Every day you shall sacrifice a young bull as a sin offering for atonement; afterwards,^[a] purge the altar by making atonement for it; pour olive oil upon it to sanctify it.
