49 if it is greenish or reddish, it is a spreading mildew and must be shown to the priest.
50 The priest shall examine it and put the object away for seven days.
51 He shall examine it again on the seventh day, and if the mildew has spread, the object is unclean.
52 The priest shall burn it, because it is a spreading mildew which must be destroyed by fire.
53 But if, when he examines it, the priest finds that the mildew has not spread on the object,
54 he shall order it to be washed and put away for another seven days.
55 Then he shall examine it, and if the mildew has not changed colour, even though it has not spread, it is still unclean; you must burn the object, whether the rot is on the front or the back.
