Leviticus 14:1-8

1 God spoke to Moses,
2 "These are the instructions for the infected person at the time of his cleansing. First, bring him to the priest.
3 The priest will take him outside the camp and make an examination; if the infected person has been healed of the serious skin disease,
4 the priest will order two live, clean birds, some cedar wood, scarlet thread, and hyssop to be brought for the one to be cleansed.
5 The priest will order him to kill one of the birds over fresh water in a clay pot.
6 The priest will then take the live bird with the cedar wood, the scarlet thread, and the hyssop and dip them in the blood of the dead bird over fresh water
7 and then sprinkle the person being cleansed from the serious skin disease seven times and pronounce him clean. Finally, he will release the live bird in the open field.
8 The cleansed person, after washing his clothes, shaving off all his hair, and bathing with water, is clean. Afterwards he may again enter the camp, but he has to live outside his tent for seven days.
