Exodus 29:29-33

29“Aaron’s sacred garments must be preserved for his descendants who succeed him, and they will wear them when they are anointed and ordained.

30The descendant who succeeds him as high priest will wear these clothes for seven days as he ministers in the Tabernacle and the Holy Place.

31“Take the ram used in the ordination ceremony, and boil its meat in a sacred place.

32Then Aaron and his sons will eat this meat, along with the bread in the basket, at the Tabernacle entrance.

33They alone may eat the meat and bread used for their purification in the ordination ceremony. No one else may eat them, for these things are set apart and holy.
