Leviticus 8:24

Then Moses brought forward the sons of Aaron, and put some of the blood on the tips of their right ears, and on the thumbs of their right hands, and on the great toes of their right feet. He then poured the blood against the altar round about.

And he took the fat, and the rump, and the fat on the belly, and the lobe of the liver, and the two kidneys, and the fat that is upon them, and the right shoulder.
