Leviticus 8:23-26

²³And when it was slain, Moses took of the blood thereof, and put it upon the tip of Aaron's right ear, and upon the thumb of his right hand, and upon the great toe of his right foot.

²⁴And Aaron's sons were brought, and Moses put of the blood upon the tip of their right ear, and upon the thumb of their right hand, and upon the great toe of their right foot; and Moses dashed the blood against the altar round about.

²⁵And he took the fat, and the fat tail, and all the fat that was upon the inwards, and the lobe of the liver, and the two kidneys, and their fat, and the right thigh.

²⁶And out of the basket of unleavened bread, that was before the LORD, he took one unleavened cake, and one cake of oiled bread, and one wafer, and placed them on the fat, and upon the right thigh.
