Leviticus 14:48-53

48If a person mends his house, the priest must look at it. There may not be any mildew. The priest will then say that it is clean.

49The person must take two birds and some wood from the cedar tree. He must take red wool and hyssop.

50The priest will bring a pot with water in it. He will hold one of the birds over the pot and he will kill it.

51The priest will take the other bird and the wood from the cedar tree. He will take the red wool and the hyssop. He will put all of them into the blood of the dead bird. He will shake the blood and water over the house seven times. This will make the house clean.

52The priest will use the birds and the wood from the cedar tree. And he will use the wool and the hyssop to make the house clean.

53Then the priest will take the living bird outside the town. He will let the bird fly away. That will make atonement for the house. The person may then live in the house again.’
