Exodus 29:22-23

Also you shall take some of the ram’s fat, the fat tail, the fat that covers the innards, the cover of the liver, the two kidneys, the fat that is on them, and the right thigh (for it is a ram of consecration),

and one loaf of bread, one cake of oiled bread, and one wafer out of the basket of unleavened bread that is before the LORD.
