Exodus 29:22-24

New Revised Standard Version, Anglicised Catholic Edition

²² You shall also take the fat of the ram, the fat-tail, the fat that covers the entrails, the appendage of the liver, the two kidneys with the fat that is on them, and the right thigh (for it is a ram of ordination), ²³ and one loaf of bread, one cake of bread made with oil, and one wafer, out of the basket of unleavened bread that is before the Lord; ²⁴ and you shall place all these on the palms of Aaron and on the palms of his sons, and raise them as an elevation-offering before the Lord.
