⁴⁹And he shall take to purify the house two clean living birds, and cedar wood, and spun scarlet, and hyssop.

⁵⁰And he shall slay one bird in an earthen vessel over running water.

⁵¹And he shall take the cedar wood, and the spun scarlet, and the hyssop, and the living bird; and shall dip it into the blood of the bird slain over running water, and with them he shall sprinkle the house seven times.

⁵²And he shall purify 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 spun scarlet.

⁵³And he shall let the living bird go out of the city into the field, and shall make atonement for the house, and it shall be clean.

⁵⁴This is the law concerning every plague of leprosy and scurf,
