Leviticus 14:55

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 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.
