Exodus 29:22-26

22“Also you shall take the fat of the ram, the fat tail, the fat that covers the entrails, the fatty lobe attached to the liver, the two kidneys and the fat on them, the right thigh (for it is a ram of consecration),

23one loaf of bread, one cake made with oil, and one wafer from the basket of the unleavened bread that is before the Lord;

24and you shall put all these in the hands of Aaron and in the hands of his sons, and you shall wave them as a wave offering before the Lord.

25You shall receive them back from their hands and burn them on the altar as a burnt offering, as a sweet aroma before the Lord. It is an offering made by fire to the Lord.

26“Then you shall take the breast of the ram of Aaron’s consecration and wave it as a wave offering before the Lord; and it shall be your portion.
