Exodus 29:29-33

29And the holy garments of Aaron shall be his sons' after him, to be anointed therein, and to be consecrated in them.

30The son that is priest in his stead shall put them on seven days, when he cometh into the tent of meeting to serve in the sanctuary.

31And thou shalt take the ram of the consecration, and boil its flesh in a holy place.

32And Aaron and his sons shall eat the flesh of the ram, and the bread that is in the basket, at the entrance of the tent of meeting.

33They shall eat the things with which the atonement was made, to consecrate [and] to hallow them; but a stranger shall not eat [of them], for they are holy.
