Leviticus 8:24-25

²⁴He brought Aaron's sons, and he put some of the blood on the tip of their right ear, on the thumb of their right hand, and on the big toe of their right foot. Then Moses sprinkled its blood against every side of the altar.

²⁵He took the fat, the fat tail, all the fat that was on the inner parts, the covering of the liver, the two kidneys and their fat, and the right thigh.
