Exodus 29:24-27

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.
