Exodus 29:24-26

24and you shall put all these in the hands of Aaron and his sons, and wave them as a wave offering before the Lord.

25Then you shall take them from their hands, add them to the burnt offering, and burn them on the altar for a sweet and soothing aroma before the Lord; it is an offering by fire to the Lord.

26“Then you shall take the breast of the ram of Aaron’s ordination, and wave it as a wave offering before the Lord; and it shall be your (Moses) portion.
