23and one slaughtered [it]; and Moses took of its blood, and put [it] on the tip of Aaron's right ear, and on the thumb of his right hand, and on the great toe of his right foot;

24and he brought Aaron's sons near, and Moses put of the blood on the tip of their right ear, and on the thumb of their right hand, and on the great toe of their right foot; and Moses sprinkled the blood upon the altar round about.
