Exodus 29:22-24

22“Moreover, take some of the fat from the ram, along with the fat tail, the fat that covers the innards, the covering over the liver, the two kidneys and the fat that is on them, along with the right thigh, because it is a ram of consecration.

23Also take one loaf of bread, one cake of oiled bread, and one wafer out of the basket of matzot that is before Adonai.

24You are to put the entirety into Aaron’s hands and the hands of his sons, and present them as a wave offering before Adonai.
