Leviticus 8:25-26
25 He took the fat, the fat tail, all the fat around the inner parts, the covering of the liver, both kidneys and their fat and the right thigh.
26 Then from the basket of bread made without yeast, which was before the Lord, he took a cake of bread, and one made with oil, and a wafer; he put these on the fat portions and on the right thigh.
