Exodus 29:22-24

Modern English Version

²² Also you shall take the fat and the rump of the ram, and the fat that covers the entrails and the lobe above the liver, and the two kidneys, and the fat that is on them and the right shoulder (for it is a ram of consecration), ²³ 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. ²⁴ And you shall put all of these in the hands of Aaron and in the hands of his sons, and shall wave them for a wave offering before the Lord.
