Leviticus 8:25-26

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.
