Exodus 29:27-34

27You shall consecrate the waved breast offering [of the ram] used in the ordination and the waved thigh offering of the priests’ portion, since it is [a contribution] for Aaron and for his sons.

28It shall be for Aaron and his sons as their due portion from the Israelites forever, for it is a heave offering. It shall be a heave offering to the Lord from the Israelites from the sacrifices of their peace offerings.

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

30That son who is [high] priest in his place shall put them on [each day for] seven days when he comes into the Tent of Meeting to minister in the Holy Place.

31“You shall take the ram of the ordination and boil its meat in a holy place.

32Aaron and his sons shall eat the meat of the ram and the bread in the basket, at the doorway of the Tent of Meeting.

33They shall eat those things by which atonement was made at their ordination and consecration; but a layman shall not eat them, because they are holy [that is, set apart to the worship of God].

34And if any of the meat of ordination or the bread remains until morning, you shall burn it in the fire; it shall not be eaten, because it is holy.
