Leviticus 8:21-23

²¹And he washed the inwards and the legs with water; and Moses burnt the whole ram upon the altar: it was a burnt-offering for a sweet savor: it was an offering made by fire unto Jehovah; as Jehovah commanded Moses.

²²And he presented the other ram, the ram of consecration: and Aaron and his sons laid their hands upon the head of the ram.

²³And he slew it; and 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.
