Leviticus 8:25-28

25Then he took the fat and the fat tail, all the fat that was on the entrails, the fatty lobe attached to the liver, the two kidneys and their fat, and the right thigh;

26and from the basket of unleavened bread that was before the Lord he took one unleavened cake, a cake of bread anointed with oil, and one wafer, and put them on the fat and on the right thigh;

27and he put all these in Aaron’s hands and in his sons’ hands, and waved them as a wave offering before the Lord.

28Then Moses took them from their hands and burned them on the altar, on the burnt offering. They were consecration offerings for a sweet aroma. That was an offering made by fire to the Lord.
