Leviticus 8:25-28

25He took the fat, the fat from the tail, all the fat on the internal organs, the lobe of the liver, the two kidneys with their fat, and the right thigh.

26He took a loaf of unleavened bread, a ring of bread made with olive oil, and a wafer from the basket of unleavened bread which was in the Lord’s presence. He put them on the fat and the right thigh.

27Then he placed all these things in the hands of Aaron and his sons. Moses presented all these things to the Lord as an offering.

28Then he took them from their hands and burned them on top of the burnt offering on the altar. These were ordination offerings, offerings by fire, a soothing aroma to the Lord.
