⁴⁹And to the cleansing thereof, the priest shall take two sparrows, and cedar wood, and vermilion, that is, a red thread, and hyssop.

⁵⁰And when one sparrow is offered in a vessel of earth, on quick waters,

⁵¹the priest shall take the cedar wood, and hyssop, and the red thread, and the quick sparrow, and he shall dip, or wet, all these things in the blood of the sparrow offered, or slain, and in the quick waters; and he shall sprinkle the house seven times;

⁵²and he shall cleanse it as well in the blood of the sparrow, as in the living waters, and in the quick sparrow, and in the cedar wood, and in the hyssop, and red thread.

⁵³And when he hath let go the sparrow to fly away into the field freely, he shall pray for the house, and it shall be cleansed rightfully.

⁵⁴This is the law of all leprosy, and of smiting,
