Leviticus 8:25-29

25He took the fat — the fat tail, all the fat that was on the entrails, the fatty lobe of the liver, and the two kidneys with their fat — as well as the right thigh.

26From 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 placed them on the fat portions and the right thigh.

27He put all these in the hands of Aaron and his sons and presented them before the Lord as a presentation offering.

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

29He also took the breast and presented it before the Lord as a presentation offering; it was Moses’s portion of the ordination ram as the Lord had commanded him.
