Leviticus 8:27-29

and he put all these in Aaron’s hands and in his sons’ hands, and waved them as a wave offering before the LORD. Then Moses took them from their hands and burned them on the altar, on the burnt offering. They were consecration offerings for a sweet aroma. That was an offering made by fire to the LORD. And Moses took the breast and waved it as a wave offering before the LORD. It was Moses’ part of the ram of consecration, as the LORD had commanded Moses.
