Exodus 29:33-35

New International Version

³³ They are to eat these offerings by which atonement was made for their ordination and consecration. But no one else may eat^(A) them, because they are sacred. ³⁴ And if any of the meat of the ordination ram or any bread is left over till morning,^(B) burn it up. It must not be eaten, because it is sacred.

³⁵ “Do for Aaron and his sons everything I have commanded you, taking seven days to ordain them.
