Leviticus 14:51-52

51Then he shall take the cedar wood and the 1hyssop and the 2scarlet string, with the live bird, and dip them in the blood of the slain bird as well as in the 3running water, and sprinkle the house seven times.

52He shall thus cleanse the house with the blood of the bird and with the 4running water, along with the live bird and with the cedar wood and with the hyssop and with the 5scarlet string.
