Exodus 29:25-27

New Century Version

²⁵ Then take them from their hands and burn them on the altar with the whole burnt offering. This is an offering made by fire to the Lord; its smell is pleasing to the Lord. ²⁶ Then take the breast of the male sheep used to appoint Aaron as priest, and present it before the Lord as an offering. This part of the animal will be your share. ²⁷ Set aside the breast and the thigh of the sheep that were used to appoint Aaron and his sons as priests. These parts belong to them.
