Leviticus 8:25-26

Then he took the fat and the fat tail and all the fat that was on the entrails and the long lobe of the liver and the two kidneys with their fat and the right thigh, and out of the basket of unleavened bread that was before the LORD he took one unleavened loaf and one loaf of bread with oil and one wafer and placed them on the pieces of fat and on the right thigh.
