⁴⁹To cleanse the house he shall take two birds, cedar wood, scarlet, and hyssop.

⁵⁰He shall kill one of the birds in an earthen vessel over running water.

⁵¹He 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.

⁵²He 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;

⁵⁴This is the law for any plague of leprosy, and for an itch,
