Exodus 29:24 KJV

22Also thou shalt take of the ram the fat and the rump, and the fat that covereth the inwards, and the caul above the liver, and the two kidneys, and the fat that is upon them, and the right shoulder; for it is a ram of consecration:

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

24And thou shalt put all in the hands of Aaron, and in the hands of his sons; and shalt wave them for a wave offering before the LORD.

25And thou shalt receive them of their hands, and burn them upon the altar for a burnt offering, for a sweet savour before the LORD: it is an offering made by fire unto the LORD.

26And thou shalt take the breast of the ram of Aaron’s consecration, and wave it for a wave offering before the LORD: and it shall be thy part.
