Exodus 29:24-26

24and put all of them in the hands of Aaron and his sons and present them as a presentation offering before the Lord.

25Take them from their hands and burn them on the altar on top of the burnt offering, as a pleasing aroma before the Lord; it is a food offering to the Lord.

26“Take the breast from the ram of Aaron’s ordination and present it as a presentation offering before the Lord; it is to be your portion.
