Exodus 29:19-20

19And thou shalt take the other ram; and Aaron and his sons shall put their hands upon the head of the ram. 20Then shalt thou kill the ram, and take of his blood, and put it upon the tip of the right ear of Aaron, and upon the tip of the right ear of his sons, and upon the thumb of their right hand, and upon the great toe of their right foot, and sprinkle the blood upon the altar round about.
