Leviticus 14:46-57

46Anyone who enters the house during any of the days that it is closed up will be unclean until evening. 47And anyone who sleeps in the house or eats in it must wash his clothes.

48If, however, the priest comes and inspects it, and the mildew has not spread after the house has been replastered, he shall pronounce the house clean, because the mildew is gone.

49He is to take two birds, cedar wood, scarlet yarn, and hyssop to purify the house; 50and he shall slaughter one of the birds over fresh water in a clay pot.

51Then he shall take the cedar wood, the hyssop, the scarlet yarn, and the live bird, dip them in the blood of the slaughtered bird and the fresh water, and sprinkle the house seven times. 52And he shall cleanse the house with the bird’s blood, the fresh water, the live bird, the cedar wood, the hyssop, and the scarlet yarn.

53Finally, he is to release the live bird into the open fields outside the city. In this way he will make atonement for the house, and it will be clean.

54This is the law for any infectious skin disease, for a scaly outbreak, 55for mildew in clothing or in a house, 56and for a swelling, rash, or spot, 57to determine when something is clean or unclean. This is the law regarding skin diseases and mildew.1”
