The priest will use the blood and the water to make the house pure. He will use the live bird to make it pure. He will also use the cedar wood, the hyssop plant and the bright red yarn to make it pure.
The priest will sprinkle the blood on the person who had the skin disease. That will make them ‘clean.’ The priest must sprinkle them seven times. Then the priest must announce that they are ‘clean.’ After that, the priest must let the live bird go free in the open fields.
