Exodus 29:28

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.
