Leviticus 14:50-57

50He shall kill one of the birds over fresh water in a clay pot.

51Then he is to take the cedar wood, the hyssop, the scarlet yarn and the live bird, dip them into the blood of the dead bird and the fresh water, and sprinkle the house seven times.

52He shall purify the house with the bird’s blood, the fresh water, the live bird, the cedar wood, the hyssop and the scarlet yarn.

53Then he is to release the live bird in the open fields outside the town. In this way he will make atonement for the house, and it will be clean.”

55for defiling molds in fabric or in a house,

56and for a swelling, a rash or a shiny spot,

57to determine when something is clean or unclean. These are the regulations for defiling skin diseases and defiling molds.
