Exodus 29:29-33

29“Aaron’s sacred garments will belong to his descendants so that they can be anointed and ordained in them.

30The son who succeeds him as priest and comes to the tent of meeting to minister in the Holy Place is to wear them seven days.

31“Take the ram for the ordination and cook the meat in a sacred place.

32At the entrance to the tent of meeting, Aaron and his sons are to eat the meat of the ram and the bread that is in the basket.

33They are to eat these offerings by which atonement was made for their ordination and consecration. But no one else may eat them, because they are sacred.
