Exodus 29:22-25

Also 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: And 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: And 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. {shalt wave: or, shalt shake to and fro} And 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.
