Exodus 29:30

26“You shall take the breast of Aaron’s ram of consecration, and wave it for a wave offering before the LORD. It shall be your portion.

27You shall sanctify the breast of the wave offering and the thigh of the wave offering, which is waved, and which is raised up, of the ram of consecration, even of that which is for Aaron, and of that which is for his sons.

28It shall be for Aaron and his sons as their portion forever from the children of Israel; for it is a wave offering. It shall be a wave offering from the children of Israel of the sacrifices of their peace offerings, even their wave offering to the LORD.

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

30Seven 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 meat in a holy place.

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

33They 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.

34If anything of the meat 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.
