Leviticus 8:25-27

25Then 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, 26and 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. 27And he put all these in the hands of Aaron and in the hands of his sons and waved them as a wave offering before the LORD.
