50 He shall kill one of the birds over a clay bowl containing fresh spring water.
51 Then he shall take the cedar wood, the hyssop, the red cord, and the live bird and shall dip them in the blood of the bird that was killed and in the fresh water. And he shall sprinkle the house seven times.
52 In this way he shall purify the house with the bird's blood, the fresh water, the live bird, the cedar wood, the hyssop, and the red cord.
53 Then he shall let the live bird fly away outside the city over the open fields. In this way he shall perform the ritual of purification for the house, and it will be ritually clean.
54 These are the laws about dreaded skin diseases;
55-56 sores, boils, or inflammations; and about mildew in clothes or houses.
57 These laws determine when something is unclean and when it is clean.
