Leviticus 8:27-29

27He put all these in the hands of Aaron and his sons and presented them before the Lord as a presentation offering.

28Then 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.

29He 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.
