Exodus 29:27-34

27And you shall consecrate the breast of the wave offering that is waved and the thigh of the priests' portion that is contributed from the ram of ordination, from what was Aaron's and his sons'.

28It shall be for Aaron and his sons as a perpetual due from the people of Israel, for it is a contribution. It shall be a contribution from the people of Israel from their peace offerings, their contribution to the Lord.

29"The holy garments of Aaron shall be for his sons after him; they shall be anointed in them and ordained in them.

30The son who succeeds him as priest, who comes into the tent of meeting to minister in the Holy Place, shall wear them seven days.

31"You shall take the ram of ordination 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 in the entrance of the tent of meeting.

33They shall eat those things with which atonement was made at their ordination and consecration, but an outsider shall not eat of them, because they are holy.

34And if any of the flesh for the ordination or of the bread remain until the morning, then you shall burn the remainder with fire. It shall not be eaten, because it is holy.
