47 And if you either slept or ate in the house, you must wash your clothes.
48 On the other hand, if the priest discovers that mildew hasn't reappeared after the house was newly plastered, he will say, “This house is clean—the mildew has gone.”
49 Then, to show that the house is now clean, he will get two birds, a stick of cedar wood, a piece of red yarn, and a branch from a hyssop plant and bring them to the house.
50 He will kill one of the birds over a clay pot of spring water
51-52 and let its blood drain into the pot. Then he will dip the cedar, the hyssop, the yarn, and the other bird into the mixture of blood and water. Next, he will sprinkle the house seven times with the mixture, then the house will be completely clean.
53 Finally, he will release the bird and let it fly away, ending the ceremony for purifying the house.
54-57 These are the things you must do if you discover that you are unclean because of an itch or a sore, or that your clothing or house is unclean because of mildew.
