Leviticus 14:49-52

49In order to cleanse the house he is to take two birds, cedar wood, scarlet and hyssop.

50He is to kill one of the birds in a clay pot over living water.

51Then he is to take the cedar wood, the hyssop, the scarlet and the living bird, and dip them into the blood of the slain bird as well as the living water, and sprinkle the house seven times.

52He shall cleanse the house with the blood of the bird, with the living water, with the living bird, the cedar wood, the hyssop and the scarlet.
