Leviticus 14:6, 14, 25, 51-52

As for the living bird, he shall take it, the cedar wood and the scarlet and the hyssop, and dip them and the living bird in the blood of the bird that was killed over the running water.

The priest shall take some of the blood of the trespass offering, and the priest shall put it on the tip of the right ear of him who is to be cleansed, on the thumb of his right hand, and on the big toe of his right foot.

Then he shall kill the lamb of the trespass offering, and the priest shall take some of the blood of the trespass offering and put it on the tip of the right ear of him who is to be cleansed, on the thumb of his right hand, and on the big toe of his right foot.

and he shall take the cedar wood, the hyssop, the scarlet, and the living bird, and dip them in the blood of the slain bird and in the running water, and sprinkle the house seven times. And he shall cleanse the house with the blood of the bird and the running water and the living bird, with the cedar wood, the hyssop, and the scarlet.
