Leviticus

He shall cause the inside of the house to be scraped all over. They shall pour out the mortar that they scraped off outside of the city into an unclean place.

They shall take other stones, and put them in the place of those stones; and he shall take other mortar, and shall plaster the house.

“If the plague comes again, and breaks out in the house after he has taken out the stones, and after he has scraped the house, and after it was plastered,

then the priest shall come in and look; and behold, if the plague has spread in the house, it is a destructive mildew in the house. It is unclean.

He shall break down the house, its stones, and its timber, and all the house’s mortar. He shall carry them out of the city into an unclean place.

“Moreover he who goes into the house while it is shut up shall be unclean until the evening.

He who lies down in the house shall wash his clothes; and he who eats in the house shall wash his clothes.

“If the priest shall come in, and examine it, and behold, the plague hasn’t spread in the house, after the house was plastered, then the priest shall pronounce the house clean, because the plague is healed.

To cleanse the house he shall take two birds, cedar wood, scarlet, and hyssop.

He shall kill one of the birds in an earthen vessel over running water.

He shall take the cedar wood, the hyssop, 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.

He shall cleanse the house with the blood of the bird, and with the running water, with the living bird, with the cedar wood, with the hyssop, and with the scarlet;

but he shall let the living bird go out of the city into the open field. So shall he make atonement for the house; and it shall be clean.”

This is the law for any plague of leprosy, and for an itch,

and for the destructive mildew of a garment, and for a house,

and for a swelling, and for a scab, and for a bright spot;

to teach when it is unclean, and when it is clean. This is the law of leprosy.
