Leviticus 8:25-28

25And Moses took the fat—the fat tail, all the fat that was on the entrails, the lobe of the liver, and both kidneys with their fat—as well as the right thigh. 26And from the basket of unleavened bread that was before the LORD, he took one cake of unleavened bread, one cake of bread made with oil, and one wafer, and he placed them on the fat portions and on the right thigh. 27He put all these in the hands of Aaron and his sons and waved them before the LORD as a wave offering.

28Then Moses took these from their hands and burned them on the altar with the burnt offering. This was an ordination offering, a pleasing aroma, a food offering to the LORD.
