Exodus 29:24-27

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.

27Consecrate for Aaron and his sons the breast of the presentation offering that is presented and the thigh of the contribution that is lifted up from the ram of ordination.
