Leviticus 8:27-29

He put all these in the hands of Aaron and his sons and presented them before the LORD as a presentation offering. Then Moses took them from their hands and burned them on the altar with the burnt offering. This was an ordination offering for a pleasing aroma, a food offering to the LORD. He also took the breast and presented it before the LORD as a presentation offering; it was Moses’s portion of the ordination ram as the LORD had commanded him.
