Leviticus 14:53

50 and he shall kill one of the birds in an earthen vessel over running water:

51 and he shall take the cedar wood, and the hyssop, and 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:

52 and he shall cleanse the house with the blood of the bird, and with the running water, and with the living bird, and with the cedar wood, and with the hyssop, and with the scarlet:

53 but he shall let got the living bird out of the city into the open field: so shall he make atonement for the house; and it shall be clean.

54 This is the law for all manner of plague of leprosy, and for a scall,

55 and for the leprosy of a garment, and for a house,

56 and for a rising, and for a scab, and for a bright spot;
