Leviticus 8:25, 26

After that, he took the fat, the fat tail, all the fat around the internal organs, the long lobe of the liver, both kidneys and their fat and the right thigh.

And from the basket of bread made without yeast, which was before the LORD, he took one thick loaf, one thick loaf with olive oil mixed in, and one thin loaf, and he put these on the fat portions and on the right thigh.
