Exodus 29:24-27

24Put all these in the hands of Aaron and his sons to be lifted up as a special offering to the Lord.

25Afterward take the various breads from their hands, and burn them on the altar along with the burnt offering. It is a pleasing aroma to the Lord, a special gift for him.

26Then take the breast of Aaron’s ordination ram, and lift it up in the Lord’s presence as a special offering to him. Then keep it as your own portion.

27“Set aside the portions of the ordination ram that belong to Aaron and his sons. This includes the breast and the thigh that were lifted up before the Lord as a special offering.
