Leviticus 8:27-29

8:27 He then put all of them on the palms of Aaron and his sons, who waved them as a wave offering before the Lord. 8:28 Moses then took them from their palms and offered them up in smoke on the altar on top of the burnt offering – they were an ordination offering for a soothing aroma; it was a gift to the Lord. 8:29 Finally, Moses took the breast and waved it as a wave offering before the Lord from the ram of ordination. It was Moses’ share just as the Lord had commanded Moses.

Exodus 29:24

29:24 You are to put all these in Aaron’s hands and in his sons’ hands, and you are to wave them as a wave offering before the Lord.
