Exodus 29:29-33

29“The holy garments of Aaron are to pass to his sons after him, to be anointed in them and to be consecrated in them.

30The son that succeeds him as kohen, who comes into the Tent of Meeting to minister in the holy place, is to put them on for seven days.

31“You are to take the ram of consecration and boil its meat in a holy place.

32Aaron and his sons are to eat the meat of the ram and the bread that is in the basket at the entrance of the Tent of Meeting.

33They are to eat those things with which atonement was made, to consecrate and to sanctify them, but a layman is not to eat them, because they are holy.
