Exodus 29:32

29 "The holy garments of Aaron shall be for his sons after him, to be anointed in them, and to be consecrated in them.

30 Seven days shall the son who is priest in his place put them on, when he comes into the tent of meeting to minister in the holy place.

31 "You shall take the ram of consecration, and boil its flesh in a holy place.

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

33 They shall eat those things with which atonement was made, to consecrate and sanctify them: but a stranger shall not eat of it, because they are holy.

34 If anything of the flesh of the consecration, or of the bread, remains to the morning, then you shall burn the remainder with fire: it shall not be eaten, because it is holy.

35 "Thus shall you do to Aaron, and to his sons, according to all that I have commanded you. Seven days shall you consecrate them.
