Exodus 29:22-24

Revised Standard Version Catholic Edition

²² “You shall also take the fat of the ram, and the fat tail, and the fat that covers the entrails, and the appendage of the liver, and 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, and one cake of bread with oil, and one wafer, out of the basket of unleavened bread that is before the Lord; ²⁴ and you shall put all these in the hands of Aaron and in the hands of his sons, and wave them for a wave offering before the Lord.
