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

As for the live bird, he shall take it together with the cedar wood and the scarlet string and the hyssop, and shall dip them and the live bird in the blood of the bird sacrificed over the running water.

The priest shall take some of the blood of the guilt offering and put it on the lobe of the right ear of the one to be cleansed, and on the thumb of his right hand, and on the big toe of his right foot.

Next he shall kill the lamb of the guilt offering; and the priest is to take some of the blood of the guilt offering and put it on the lobe of the right ear of the one to be cleansed, and on the thumb of his right hand, and on the big toe of his right foot.

and he shall take the cedar wood and the hyssop and the scarlet string, and the living bird, and dip them in the blood of the slain bird as well as in the running water, and sprinkle the house seven times. So he shall cleanse the house with the blood of the bird and with the running water, along with the live bird and the cedar wood and the hyssop and the scarlet string.
