Leviticus

⁵²and he shall cleanse the house with the blood of the bird, and with the running water, and with the living bird, and with the cedar wood, and with the hyssop, and with the scarlet: ⁵³but he shall let go the living bird out of the city into the open field: so shall he make atonement for the house: and it shall be clean. ⁵⁴This is the law for all manner of plague of leprosy, and for a scall; ⁵⁵and for the leprosy of a garment, and for a house; ⁵⁶and for a rising, and for a scab, and for a bright spot: ⁵⁷to teach when it is unclean, and when it is clean: this is the law of leprosy.
