Exodus 29:23-30

23along with one loaf of bread, one cake of bread made with oil, and one wafer from the basket of unleavened bread that is before the LORD. 24Put all these in the hands of Aaron and his sons and wave them before the LORD as a wave offering. 25Then take them from their hands and burn them on the altar atop the burnt offering as a pleasing aroma before the LORD; it is a food offering to the LORD.

26Take the breast of the ram of Aaron’s ordination and wave it before the LORD as a wave offering, and it will be your portion. 27Consecrate for Aaron and his sons the breast of the wave offering that is waved and the thigh of the heave offering that is lifted up from the ram of ordination. 28This will belong to Aaron and his sons as a regular portion from the Israelites, for it is the heave offering the Israelites will make to the LORD from their peace offerings.

29The holy garments that belong to Aaron will belong to his sons after him, so they can be anointed and ordained in them. 30The son who succeeds him as priest and enters the Tent of Meeting to minister in the Holy Place must wear them for seven days.
