Leviticus 8:27-29

And he put all these in the hands of Aaron and in the hands of his sons and waved them as a wave offering before the LORD. Then Moses took them from their hands and burned them on the altar with the burnt offering. This was an ordination offering with a pleasing aroma, a food offering to the LORD. And Moses took the breast and waved it for a wave offering before the LORD. It was Moses’ portion of the ram of ordination, as the LORD commanded Moses.
