Leviticus 14:2-9

2“These are the regulations for any diseased person at the time of their ceremonial cleansing, when they are brought to the priest:

3The priest is to go outside the camp and examine them. If they have been healed of their defiling skin disease,

4the priest shall order that two live clean birds and some cedar wood, scarlet yarn and hyssop be brought for the person to be cleansed.

5Then the priest shall order that one of the birds be killed over fresh water in a clay pot.

6He is then to take the live bird and dip it, together with the cedar wood, the scarlet yarn and the hyssop, into the blood of the bird that was killed over the fresh water.

7Seven times he shall sprinkle the one to be cleansed of the defiling disease, and then pronounce them clean. After that, he is to release the live bird in the open fields.

8“The person to be cleansed must wash their clothes, shave off all their hair and bathe with water; then they will be ceremonially clean. After this they may come into the camp, but they must stay outside their tent for seven days.

9On the seventh day they must shave off all their hair; they must shave their head, their beard, their eyebrows and the rest of their hair. They must wash their clothes and bathe themselves with water, and they will be clean.
