Leviticus 14:6, 7, 17, 28, 51, 52
And he is to take the live bird together with the cedar wood, scarlet yarn, and hyssop, and dip them into the blood of the bird that was slaughtered over the fresh water. / Seven times he shall sprinkle the one to be cleansed of the skin disease. Then he shall pronounce him clean and release the live bird into the open field. / And the priest is to put some of the oil remaining in his palm on the right earlobe of the one to be cleansed, on the thumb of his right hand, and on the big toe of his right foot, on top of the blood of the guilt offering.
