Leviticus 8:24-28

He also had Aaron’s sons come near; and Moses put some of the blood on the lobe of their right ear, and on the thumb of their right hand and on the big toe of their right foot. Moses then sprinkled the rest of the blood around on the altar.

He then took the fat, and the fat tail, and all the fat that was on the entrails, and the lobe of the liver, the two kidneys and their fat, and the right thigh.

And from the basket of unleavened bread that was before the Lord, he took one unleavened cake and one cake of bread mixed with oil and one wafer, and placed them on the portions of fat and on the right thigh.

He then put all these on the hands of Aaron and on the hands of his sons, and presented them as a wave offering before the Lord.

Then Moses took them from their hands and offered them up in smoke on the altar with the burnt offering. They were an ordination offering for a soothing aroma; it was an offering by fire to the Lord.
