Exodus 29:24

22Also you shall take some of the ram’s fat, the fat tail, the fat that covers the innards, the cover of the liver, the two kidneys, the fat that is on them, and the right thigh (for it is a ram of consecration),

23and one loaf of bread, one cake of oiled bread, and one wafer out of the basket of unleavened bread that is before the LORD.

24You shall put all of this in Aaron’s hands, and in his sons’ hands, and shall wave them for a wave offering before the LORD.

25You shall take them from their hands, and burn them on the altar on the burnt offering, for a pleasant aroma before the LORD: it is an offering made by fire to the LORD.

26“You shall take the breast of Aaron’s ram of consecration, and wave it for a wave offering before the LORD. It shall be your portion.
